What it is
Simply change the head to easily care for your heel calluses and nail care with "file and polish." 1. "Calling head" Formulated with diamond powder, known as the hardest callus remover, it quickly removes hardened calluses, leaving your heels smooth. 2. "Electric nail file" Simply place it on your outgrown nails! No force required, comfortable and safe. Even hard nails on your hands and feet are filed, not cut, for a beautiful finish with a natural curve. 3. "Nail polishing head" Use two different types of files to smooth the nail surface and polish it for a shiny, beautiful nail. Battery-operated for easy portability.

To finish, hold it in the opposite direction to file for a smoother finish. Nail Polish (Buff your nails): Attach the nail file head and turn the switch on. First, place the green file side horizontally on your nail to smooth out any unevenness on the surface. Then, apply the white file side and polish the surface of your nail until you achieve your desired shine.
