I bought these in Santa Monica during my trip to Los Angeles. I cut the tags off because I intended to use them, but I only tried them on in the store. The size is listed as S, which is a foreign size. I usually wear shoes in the 23-23.5cm range. I plan to ship via Yu-packet Post. Please be aware that I will need to slightly compress the thong to fit it in the package. Please understand that this is a foreign product and has been stored at home before purchasing.
