The ergonomically shaped "Softtouch" Titania Double-Sided Foot Callus File has a coarse and a fine ceramic surface for the gentle and thorough removal of corns and calluses. The non-slip grip and the curved shape make removal easy even on difficult to reach spots. To achieve optimal results use this product on dry skin. Use the coarse ceramic surface first to remove hard corns and calluses. Then use the fine ceramic surface to give a soft and gentle smooth finish. Both ceramic surfaces are easily cleaned using a nailbrush under running water.
