Feels amazing in your hands, helps with focus, anxiety, and keep my hands busy. Durable and goes back to original shape instantly. the best āstress ballā as I used it at the dentist during a dental clean. Small enough to sit in your jacket pocket to be discreet to fidget with. Best ever! Iāve gifted them to friends and they love it too! I have one in my car, my bag, my office and at home. Iāve purchased many of these and will continue to only buy this brand from now on.
