Yellow Door | Interlocking Sensory Stones

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, or four positions.

The set contains eight stones (four pairs) measuring 75mm each.

Age 18mths+.

Cast from resin, these pebbles are robust enough for messy play and mark making, both indoors and outside.
