The ergonomically shaped "Softtouch" Titania Double-Sided Foot Callus File has an emery surface and a pumice sponge for the soft 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 with the "Softtouch" Titania Double-Sided Callus File, use the emery board first on dry skin to remove hard corns and calluses, then use the pumice sponge on wet skin to give a soft and gentle smooth finish. The file can be cleaned easily using a nailbrush under running water.
