CALLUS CARE SANDING BLOCK This tool was developed to take care of dead skin cells(callus) in the palm of your hand. If proper care is not taken for the calluses on your palms, they may tear unexpectedly, leading to significant injuries. This condition is commonly referred to as a "climber's flapper."
