Introducing an exciting new range that utilises the power of glow crystals contained within a polymer based material. Each piece within the range can be seen in the dark and recharged by exposure to the sun and ambient light. The Glo material is a safe non-toxic material which is CPSIA and REACH compliant. Perfect resources for children with additional needs or younger children within a sensory den environment. This set of 4 assorted colour triangles feature a hook and loop so they can be hung up in your sensory den like bunting! Children can also trace around the glo ribbon edge to reinforce shape recognition. Size of each triangle 20 x 24cm.
