The Detonator is a special 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 weighs 50 grams.
