Finally - a fidget that comes with a cover that can be removed for laundering! Rectangular shaped to fit neatly in the hand, you can't help but to squeeze it! The insert is a water-based gel that can be warmed in warm water to get an added tactile sensation. Comes with a wide elastic piece that fits over the hand to keep the Gel-Grip from being dropped. Fits nicely into a pocket or a back pack.
