Ideal for exploring matching and symmetry, these pairs of interlocking 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 and four positions. The set contains eight stones (four pairs) measuring 75mm each. Cast from a unique mix including real stone, these pebbles are durable for many messy play, printing and mark making activities both indoors and outside. Each jar comes with a leaflet of suggested sensory play activities written by Wendy Usher.
Ages 3+, Choking hazard, small parts. Not for children under 3 years of age.
