Dr. Scholl Dr. Scholl Electric Callus Remover File Foot Care Roller Pink Used Diamond Extra (Coarse) This is a roller head that gently removes particularly hard calluses. Operation confirmed. The purchase date is unknown. The white parts are yellowed, and the red part of the handle below has black stains in places (last image). I will include the roller head in the image, but it has been used many times, so the effect may be limited. If it is not effective, dedicated replacement heads are sold, so please replace them yourself. The instruction manual in the image will also be included for shipping. Please understand that this is a used item with these stains and scratches before purchasing. Requires 4 AA batteries. Please prepare batteries. Rarely, there is a possibility of changing from Yu-Yu Mercari delivery to Raku-Raku Mercari delivery.
