Dr. Scholl's™ Callus File instantly removes the build-up of callus and hard skin with dual action for soft and smooth feet. The coarse surface safely removes rough, dry or hard skin, while the finer surface smooths the skin, leaving it softer and more refined. An easy grip handle makes filing easier, and the uniquely shaped file reaches difficult curved contours so it is hygienic, durable and simple to keep clean. Make sure your feet are clean and dry, use the coarse side to remove hard skin, then finish with the finer side. The experts at Scholl recommend softening first and then removing hard skin, so for best results use Scholl Hard Skin Softening Cream and regularly remove hard skin with this file. After use, wash the file with warm water and leave to dry naturally. Pack Contents 1 file. Safety Warning For use on hard and callused skin on the feet only. Use only on dry skin. Stop using if skin becomes sore or inflamed. Do not use if skin is broken or irritated. If dropped onto a hard surface, the metal heads may become dislodged.
