Roll a Ball Fiddle Tool: Large
Each ball changes colour with a gentle roll of the fingertip.
These are designed as a mathematical aid, similar to an abacus, but this clever tool provides sensory feedback with a tactile smooth movement, auditory and visual feedback which lends itself as a non-goal orientated fine motor fiddle tool for those who find repetitive movement calming.
Supervise use at all times, this is not a toy.
