A great sensory fidget choice for scab and skin pickers (dermatillomania), fingernail biters, hair pullers (trichotillomania), and for those who crack their knuckles. Sensory Stones are a wonderfully subtle and durable, pocket-sized fiddle or desk toy for all ages, 6-up. *Stone colors and shapes will vary.
