Meet 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 304 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.
Not suitable for 3 years and under due to small parts & choking hazard.
