This sensory board has approximately 10" x10" of an intriguingly scratchy, glittery surface for tactile exploration. Curious, sensory seeking fingers can feel the bumps of the sparkly rhinestones and experiment with the color variations in different light. Perfect to engage the senses for those with a need to fidget, who calm through repetitive movements, or who seek unique visual stimulation. This glitter mat is inset into a pine frame, so the overall item measures 13 3/8" square and can be wall mounted. Great addition to home, school, or clinic setting.
