This is preferred file for the nail technicians and salon professionals but it is also the ultimate foot care tool to speed up your at-home foot care routine. The double-sided file has both a coarse side and a fine side. This is designed to speed up and make the callus removal process more efficient, by sloughing off multiple layers of dry skin and calluses with each filing motion. Sterilizable, easy to clean and multi-directional stainless steel pedicure foot file. The time required for foot care will be reduced significantly, as cracked and callused skin will be removed faster, using less physical effort.
