Thank you for viewing. Size: Approximately 23cm Each item is a handmade, remade product. Since these are not ready-made products, please allow for slight variations. Please refrain from purchasing if you are concerned about minor imperfections. Because the thong is not sewn on, you can adjust and cut it to your preferred length. It may feel tight at first, but it will conform to your feet after wearing it for a day. If it becomes loose, you can retie the knot at the front to tighten it. You can wash it in a laundry net.
