Ideal for exploring, matching and understanding symmetry, these pairs of sensory stones are designed so that each pair interlocks in a different way, from concentric circles that 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 inches, each of which can be used for a wide variety of sensory play and mark-making activities.
