Dr. Scholl's ProSharp Micro Lime is an effective, yet gentle (so gentle, it won't burst a balloon!) stainless steel file that removes rough, dry skin and calluses to reveal soft, smooth skin. It collects skin shavings for no mess and it is translucent, so you can see shavings accumulate as you file. It is designed to fit well in hand. Included are smoothing pads that provide the finishing touch.
