Spinners are meant to be felt, so that visual attention can be focused elsewhere. They are helpful with keeping hands busy while the mind thinks. We manufacture our spinners with premium stainless steel bearings which are far superior than hybrid bearings which you will find everywhere. Stainless steel bearings are more expensive but allow for a much smoother and long lasting spin. If you buy our spinner and don't agree that it is far superior than any other spinner on the market then we will refund your purchase in full.
