A dual-sided foot file, contoured for excellent ergonomic function, comfort, and control. The Sole Mates Design brings you the benefits of two expert tools, compactly stored, clean and protected, as one unit. One side is a professional-quality stainless steel micro-file for gentle, quick, easy removal of calluses and rough dead skin. The second side is a high-quality nickel finishing file to buff skin, for touchably soft smoothness. The patented magnetic design facilitates easy, fumble-free operation and makes it virtually impossible to lose either tool . Strong, built-in magnets are concealed and secured inside each piece, for a slim, durable, portable result. .
