Educational Colours Cotton Sand is a fun and exciting sensory activity for children. The unique sand-like texture can be stretched, squeezed, pinched, pulled apart, moulded and seamlessly re-joined whilst maintaining an even resistance. Bright colours make it appealing for children to create fun artwork. Playing with Cotton Sand is a sensory experience and helps children develop hand-eye coordination and fine motor skills, making this a great activity for the classroom and home. Large, re-usable tubs for easy storage and available in 4 colours!
