Interlocking Sensory Stones


Ideal for exploring, matching and understanding symmetry, this set of sensory stones are designed so that each pair interlocks in a different way. The concentric circles can be continually twisted to shapes that can be interlocked in two, three or four positions.

The set contains eight stones (four pairs) measuring 3", each of which can be used for a wide variety of sensory play and mark-making activities.
