Yellow Door - Interlocking Sensory Stones books_for_kids Nobel Peace Prize nominee LoujainIdeal 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, each of which can be used for a wide variety of sensory play and mark making activities. Age 18m+.
