Size: Approximately 23cm 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. The thong is not sewn in, so you can adjust and cut it to your preferred length. It may feel tight at first, but it will conform to your foot 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.
