Nishibe Chemical No. 2012 Sea Sun Ladies Black M New Size is around 23cm, but the thong is relatively loose, so it should be okay for those around 24cm. Sole length: Approximately 23.7cm Shipped via anonymous Yu-Packet Post from Yu-Yu Mercari. Simple packaging, just placed in an opaque plastic bag and sealed with tape. The thong part will be compressed when placed in the postal box. While there shouldn't be any issues with the material of the product, please refrain from purchasing if you are concerned about this shipping method. Multiple items cannot be shipped via Yu-Packet Post, so it is not eligible for combined shipping.
