This is a MUJI nail file. Retail price: 550 yen I carried it around for emergencies, so I haven't used it much, but I kept it in my bag pocket, so it has some minor scratches and dirt in the crevices. I'll give it to someone as is. It's a stainless steel folding nail file, and it's a convenient size for carrying around. - Product name: Stainless steel folding nail file - How to use: Convenient for shaping nails and finishing fine details Thank you for looking.
