Size: Approximately 22cm Each item is a handmade, remade product. Since these are not mass-produced items, please allow for slight variations. Please refrain from purchasing if you are overly concerned about minor imperfections. Because the thong is not sewn in, you can adjust and cut it to your preferred length. They may feel tight at first, but they will conform to your feet after a day of wear. If they become loose, you can retie the knot at the front to tighten them. You can wash them in a laundry net. When purchasing multiple items, we will prioritize shipping methods that reduce shipping costs. For bulk purchases, we offer a discount: if you purchase two or more pairs and confirm with a comment before purchase, we will discount each pair by 100 yen.
