Feels good on your young one's hand, and a great way to give an all-over massage to relieve stress and tension. Have child or student wear the mitt before writing activities. Great tool for providing sensory input before daily activities or use for calming an over-stimulated child. The mitt offers a choice of two sensual materials: a velvet-like cloth on one side and synthetic sheepskin on the other. Since the unit is pressure activated, no on-off switch is needed. Requires 2 AA batteries (not included).
