Callus Performance® trims just enough of the callus in order to strengthen the area in a more efficient way, this way preventing it from ripping again. This simple to use tube has a high performing blade for trimming on the top and a file in the back used to smooth the surface of your hand. This process will not weaken the skin keeping the callus from ripping and causing painful irritation and bleeding.
