Children love handling stones and this set of 16 tactile threading pebbles will invite sensory play. Develop early math and fine motor skills as children sort and sequence the stones by shape, color and texture. Each set includes 16 threading pebbles in four different shapes, colors and textures plus two laces (measuring 24″). Pebbles measure 1.5 inches and are made from a robust stone and resin mix. Age 2+.
