Hard-type care set to alleviate the pain of ingrown toenails. - Product Name: Ingrown Toenail Block L Set Hard - Country of Manufacture: Japan - Purpose: Ingrown toenail care - Precautions: Instructions for use are included - Accessories: Dedicated pin and guide sheet Thank you for viewing. I bought this at a discount at a drugstore, but after checking the size at home, it was clearly the wrong size and I couldn't use it. It is unused. Also, because it is a leftover item, there are some scratches on the back (as shown in the photo). Thank you for your understanding.
