Ideally suited to those that like strong sensory input. The Kaiko Wrist Spikey Fidget is one of our most popular fidgets for those who need deep and focused pressure to assist with self-regulation

The Kaiko wrist spikey is discreet to wear and is primarily used as a harm minimisation tool that provides 'hurt without harm'. We highly recommend watching the video on various ways to use both the finger and wrist spikey as the most effective for replacement of S.H. is the least obvious often. Highly recommend if getting it for this prupose the Spikey Set as it has both wrist and finger spikeys.  

Also frequently used to minimise picking at  skin, fingernails, fingers & clothing. 

We have had customers who’ve bought the wrist spikey fidget from us and told us it has been the best tool to help them warding against tendency to S.H, 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.   

"Discreet enough that it looks like a scrunchy or bracelet, it makes it easy to wear to work. I am finding it super helpful during the day for a deeper sensory input, and it has reduced my skin picking when at work. Love it! Isabella K Aug 2023"

"These spikeys are amazing and I wish they had been invented decades ago Elizabeth S Sept 2023"

It's important to watch the video here on ways to use so you/they understand how to achieve what you/they need  in terms of 'ouch' 😊 


The Kaiko Spikey for wrist 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 & disturbed sensation in arms and muscles. Please consult your treating clinician regarding specific use for your specific condition.

They come in a range of sizes and NOW also in colours. Colour versions can be found in separate listings.   It is made of a powder coated carbon steel metal that is 'woven' to be stretchy and flexible.

If wanting to wear it all day we recommend for most (youth and adults) that the Large, Large PLUS A BIT or the XL be purchased.  More details below re sizing.

Some ways to use the wrist spikey...

  • Roll up & down the arm
  • Rub between two palms
  • Hold in one or two hands to fidget
  • Wear on wrist or ankle & flick
  • Place on wrist or ankle & twist around (similar to a 'Chinese burn') applying varying degrees of pressure dependent on preference. This technique has been particularly helpful for some in minimising self harm. It can provide the 'hurt' without the harm to the skin. 
  • Rub it on parts of body to replace picking, such as lips

Please note if wearing the wrist spikey for any period of time that it is important to monitor the skin to ensure it it is not compromising circulation. Many who like this also like the Kaiko Spikey for finger.

Also touted to have remedial benefit, stimulating acupressure points & assisting with circulation. These are stretchy but firm.


How do I SELECT the Right SIZE?

Kaiko Spikey for wrist comes in 6 sizes.

If wanting to wear it all day we recommend for most (youth & adults) that either the Large plus a bit or the XL be purchased. If wrist is tiny then the Large, if small/medium size then Large 'plus a bit'. More details below.

The sizing selected for the wrist spikey is very personal. Many of those that have tried it and find it helpful end up getting all 4 smaller sizes and use in different contexts/situations.  At first glance, it’s easy to assume sizing selection is best based on size of wrist or age of person using it. This is certainly one contributing factor, however over time its become clear that is isn't the only thing to consider.

Its so important especially with the wrist spikey to select best size for purpose.
The wrist spikey is used in used 2 main ways –

1. for high sensory input rolled up and down arm -The small & medium are great for strong input, but generally not comfortable to wear all day, more a 'use as required and then store away' size.  The smaller, the more sensory input it provides when rolled.

2. for harm minimisation /high input when distressed (twisted and pressed into wrist buy other hand in the moment of need) – for this you want the product to be wearable and literally on hand as needed.

To wear it all day you want it to not band or create restriction. When using it in this way the size isn’t what delivers the high input, it’s the pressure on twisting that does.  SO a comfortable wearing sizes is what you're best to select.

For very petite wrists the large is usually ideal  but for your average child & adult it’s the Large 'plus a bit' or the XL that is best. The XXL for larger/chunky wrists or for use on ankles/thighs.

Essentially if twisting it around wrist the same amount of input can be achieved using any of the sizes.  It is the pressure from the other hand that creates the degree of "ouch"not the SIZE of the spikey.  

If unsure, we are happy to chat regarding re your specific needs if that would be helpful.


The unstretched lengths of each if they were undone (so internal circumference) are:

SMALL: 12.5 cm length - super intense for adults or for tiny child wrists.  This is more for intense input on roll, not all day wear.  

MEDIUM: 14.5cm length  - this is a great size for intense input for adult wrists to use as needed, then take off.

LARGE: 17 cm length - For all day wear for younger children or for petite wrists.

LARGE 'PLUS A BIT': 18 cm length - For all day wear for youth and average size wrists.

XL: 20.5cm length for the XL - this often the best size for ALL DAY wear for most teens & adults.

XXL: 24cm length -This is suitable for ankles and very large wrists & upper arm.  

Care & use of your spikey:


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. 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.   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.

The finger spikey isnt 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.  


  • Age 3+ (not suitable for under 3’s)
  • Includes storage container
  • Range of sizes & colours
  • Expandable carbon steel metal material
  • The metal is highly durable but can be over stretched if used not in accordance with its typical use by rigorous stretching. It is not meant to be pulled significantly so may not suit some that like to pull things apart. It will not recover if over stretched.
