Unlike other quick fist bands or joint protectors, these TITLE Boxing Donuts gel knuckle donuts have been designed to target and protect each joint individually. Not only do they reduce impact with soft foam or gel over the top of your fist, they eliminate it by creating a circular frame around each "sensitive" or injured joint. This frame and the surrounding joints carry the load until the sore joint heals by applying pressure to the areas AROUND the sore joint, thus taking all impact completely away from the injured joint. Sold in a pack of four. Two single Knuckle Donuts and one double to protect two injured areas at once.
