Our dual support Groove Stone wearable support has been 'built' ground up by Kaiko. It can be worn two ways... as a necklace &/or as a keyring attachment.  

This rubbing tool is sleek & simple in design yet impressive in sensory input.  They have a smooth indent in the centre of one side which can be 'massaged' when feeling overwhelmed or anxious and may assist with focus. Applying pressure with the thumb can also be quite grounding.
