Our amazing Kaiko Spikey fidget has been an instant favourite! It provides firm and textured sensory feedback when rolled up and down the finger. It is touted to have remedial benefit, stimulating acupressure points & assisting with circulation. These are stretchy but firm.
It is particularly good for those that pick and bite as the 'bitey' sensation stimulates in a similar way without the harm.
Please note if wearing the spikey for any period of time that it is important to monitor the skin to ensure it is not compromising circulation.
You can slightly stretch the metal, working around it to create a looser feel if preferred. Needs to be done bit by bit and section by section to create an even stretch. (See video). Please note once stretched it cannot be unstretched.
Ideally suited to those that like strong sensory input. The Kaiko Wrist & Finger Spikey Fidgets are one of our most popular fidgets for those who need deep and focused pressure to assist with self regulation.
It is made of a powder coated metal that is 'woven' to be stretchy and flexible.
It is an ideal fidget for those who pick at their skin, fingernails and clothing.
We have had amazing feedback regarding this tool. Especially for those who live with anxiety. We have had particularly good feedback from those who pick or self-harm. Indeed, we have had customers who’ve bought the wrist spikey fidget from us and told us it has been the best tool as it provides 'ouch' without damaging the skin. Of course, the spikey fidget does not replace accessing professional help. It is a useful tool for the kit-bag.
The Kaiko Spikey helps with self regulation, calming, focus, concentration, tactile awareness and as a substitution for unhealthy/unhelpful behaviours.
We have also had a number of customers report it being helpful in reducing pain, swelling & disturbed sensation in fingers. Please consult your treating clinician regarding their use for your specific condition.
The spikey material is not designed to be over stretched/ over extended using both hands. If overstretched it will become out of shape and not return to its original form. Thus, not suitable for those that like to pull at things with two hands, like to pull things apart or generally like to test limits of products.
If wanting to wear it or alter sensory input you can gently over stretch it to increase its size. To do this take your time and very slowly work around ring with both hands putting tension on metal. Over stretching will cause it to loose shape and it will not rebound.

The bearing moves, as does the chain around it. Feels great rolled between two hands or used one handed - the options are endless with this one. When using two handed helps stabilise the core & minimise wriggling around.
Roll it between palms for a scratchy/tickly sensation.
This helps stabilise the core for wriggly bodies & those that have trouble sitting still. Also can be rolled in fingers or spun.
The Kaiko Fidget range is incredibly popular for older children, teenagers and adults. They are simple in design using stainless steel metal parts which give them a funky look and feel and also mean they do not break easily.
These small & discreet & perfect to keep in your pocket & take anywhere! They are quiet making them ideal for the workplace, travel or the classroom.

We have been working on the Hailstorm Fidget for some time now. Modelled off our Pinart tool, this is NEXT LEVEL! you can toss it over and over in the hand, 'feather' fingers underneath, shake, tip & even spin. The sound is sooo satisfying and the 37 moving pins gently 'tickle' the fingers & hand. These are hand crafted, with each pin being individually mounted in the overall casing. Small enough for the pocket, its packed with stimming JOY. Not silent so not great for meetings and the classroom but not so loud that its super annoying either. I would describe it as a soft tinkle, kind of like hail on metal, thus its name.
Made from Stainless Steel and Aluminium, weighing 100grams. Comes in a gorgeous window display tin.

This is a lovely weighted product that is very soothing as it rotates when you spin it. Typically used by holding the two moving ends of the spinner with your thumb and pointer & spinning the main body (see video).
Note this cube has 3 parts that can be pulled apart - two smaller spinning sections with a small magnetic disc which sits internally when together. If taken apart easily
A great visual stim which is quite mesmerising to watch spin.

These are our brand new subtly textured twist on our original hand rollers. Made from zinc alloy, this sensory support functions as both a weighted product and fidget. The texture adds a new sensory dimension and the texture can also be used as a picking support.
It is our most recommended weight for teens and adults clinically (unless there is hand function issues for example).
It comes in a zip-up black case for great storage. Amazing for those that need to constantly keep hands busy & to assist with agitation and anxiety.
Rotate in your hand, roll between your palms or roll to massage are three great ways you can use them. To gain an idea of how they feel to use - if you have some fat textas on hand place two in the same hand, side by side, and rotate around themselves.
Some like to put the metallic ones in the fridge between uses.
Also helpful for hand function & we have had great outcomes using with individuals with dementia, Parkinson's, MS and other hand function difficulties.
We get asked frequently if these are helpful for carpel tunnel. It is important to seek your treating dr/ therapists opinion, but often they can be helpful.
Hand squeeze exercises and tendon glide action are two exercises that are used for it and both are/can be emulated with the hand roller. Wrist stretch with weights is another and the hand roller can be used for that too. Generally best to keep selected weight to the lighter styles (180 gram or 100 gram). You may feel a gentle pull or stretch during use. However, should stop if experiencing any pain.

Slim and 'soft' to touch, yet weighted. These are now back by request. These are a heavier version of our slimmer, non metallic hand rollers. Has the weight needed but a slimmer profile in the hand. Some prefer a non metallic feel so this is perfect.

These are amazing, hard to put into words how wonderfully satisfying these are. They rotate around in the hand, are discreet and therapeutic. Great workplace tool! Great for anxiety and also hand function.

If choosing for a child 10 or younger - the 100 gm generally the better one to select, however it is personal. For 10 and up the heavier weights 160/180/250/260/305 are often preferred, although many adults like the lighter ones also. Most report the heavier ones better to assist with Anxiety.
The lighter weights also better for those that have reduced hand function.
We have many people with dementia find these helpful for decreasing agitation.

Mini Hand Rollers by Kaiko Fidgets - textured & smooth options available
We are so excited by these. Many have requested a more 'in pocket' size for our hand rollers. So we created the mini range. With both smooth and textured options, these are a wonderful sensory support for ANY age.
Smaller both in length and diameter than our orignial hand rollers, these feel amazing in the hand and are not too large for the pocket. The textured one can also be 'picked' - as a picking support. The textured version feels quite different to the touch compared to the smooth one. It is likely for large hands these will feel too small, but perfect for average to small adult hands and for children.
Also available as a duo set in a gorgeous window tin.

Meet our newest metal fidget The Detonator. It is a multifunction sensory support.
Its designed to be cradled between the pointer and middle fingers whilst using the thumb to roll and/or press and click (with minimal sound) the roller component. The hidden gem of this support is that is has a textured finish on its base which can be placed on skin (for example inside of arm or palm) and twisted for high sensory input or 'ouch'. It can also be picked & scratched at, making it a tool for harm minimisation. You can also use it to roll into the palm.
It is made from stainless steel and is nicely weighted at 50 grams. It comes in a window display tin. A stunning gift however good luck wanting to give it away and not keep it for youself. We soft launched it recently at Comic Con and it created quite a stir.
Not suitable for children under three years old.

Ideal package for the fidget lover. Amazing range of sensory tools, from super soft (caterpillar) to high sensory input (spikey) & everything in between.
We all have different sensory preferences, what you like and the next person will vary, often dramatically. The idea of the works kit is that it covers a very full range of sensory preferences, so there is always one or often many that tick the box completely for each of us.
Perfect if you want to work out which ones best suit.

A best seller - very compact and feels wonderful between the fingers. Rapid spin, which is super quiet yet very satisfying. The Cog fidget fits in a pocket and is very discreet. It is a quiet fidget, making it ideal for the workplace, travel or the classroom.
This has a super fast spin, soft vibration & slight hum which is amazing. Rolling the cog over hands and fingers gives great sensory input.
Similar to a fidget spinner only much smaller. It is easily operated one handed. Please note that you need to tighten the two flat metal parts up from time to time. They just screw together holding the cog in the centre.

The amazing NEW Kaiko TIGHTER finger Spikey fidget has been an instant favourite! It provides firmer sensory feedback to our original finger spikey when rolled up and down the finger. It is great for those that like a firmer, tighter input. These are stretchy but firm.
It is particularly good for those that pick and bite as the 'bitey' sensation stimulates in a similar way without the harm. Comes in 9 colours & 2 sizes.
When selecting a size its not so much about hand size but more about level on constriction you prefer. The 'tighter' spikey is much firmer to roll. If using it to twist around finger or clench fist when its on for "ouch' then the bigger of the two is better generally.
Some ways to use the spikey...
Please note if wearing the spikey for any period of time that it is important to monitor the skin to ensure it is not compromising circulation.
If wanting to wear it or alter sensory input you can gently over stretch it to increase its size. To do this take your time and very slowly work around ring with both hands putting tension on metal. Needs to be done bit by bit and section by section to create an even stretch. (See video). Over stretching will cause it to loose shape and it will not rebound. Please note once stretched it cannot be unstretched. Thus, not suitable for those that like to pull at things with two hands, like to pull things apart or generally like to test limits of products. Over time the colour may wear/fade, especially if sanitiser/hand creams etc are used.
The finger spikey isn't designed to be twisted back and forth on itself If twisted/rotated it can undo at the join and generally cannot be reconnected. This is not a product fault rather it being used not as intended/within the products limitations.

Like moving in patterns & keeping your fingers busy?? Then this is the fidget for you!!
This product is a super high quality premium version. With magnet strips nearly twice that of competitors. They were specially chosen out of many other types due to the quality, robustness and fantastic feel! We have even had them made especially for us in a platinum sliver finish to suit teens and adults that prefer a more subtle finish.
The ways you can use these are endless. You can even add sets together for a more spectacular fidget! You can put one on each finger and move around, or have one floating free on the magnets and spin it round and round! It allows you to be creative, and use it just how it works best for you!
It not only fits over your fingers, but its also great just in the palm of your hand to spin around and click them together over and over again!
Not a silent fidget, so not suitable, in my opinion for a work meeting or classroom, but a great sensory tool generally.
Very satisfying!

NON STICKY, STRETCHY SENSORY FUN
Amazing take on our stretchy sand. This is next level. Stretchy without being sticky and smells amazing! It feels amazing. It is similar to kinetic sand but stretchy. It is super satisfying. I promise this isn't just for kids! Adults love it also! This container is perfect hand size.
Each unit Approx 132 grams however can vary. We use premium quality In Essence essential oils. All hand blended here in Melbourne. Typically the scent is sent in the colour shown, however if unavailable we substitute the colour to closest match. The correct scent will still be in the product.
The sand itself is non toxic but it is not for eating. Some essential oils can be toxic. There is a very low amount in the sand however please note if ingested so please seek assistance on the poison line ph 13 11 26.
Please note there can be varience in how the sand stretches between batches and this is usual and not a fault. It is possible to get two different colours that feel different, again variance is common and an inherent part of how these are. Over time they can lose their stretch. They are a consumable product. Once they start to crumble it generally means they’ve lost their stretch. Over time, with frequency of use and depending on things like hand cream/sanitiser/natural oils on hands this can happen as they aren’t full of chemicals to hold it. Colours can vary between batches & texture may vary slightly from colour to colour.
Also note if hands are wet, have sanitiser/moisturiser recently applied or similar colour may come off on hands or surroundings as moisturizer can impact the sand itself. Common sense regarding how and where you use this is important.
Non Toxic but not suitable for children under the age of 3 years.
