These are Bamboo Tora's bamboo skin slippers. I loved them so much, I bought too many. They're incredibly durable and comfortable, with a refreshing, dry feeling on your soles. I've been using them for about 10 years. They're so tough, they don't even break when worn outside, haha. The thong is also soft and allows for stress-free wear. I'm selling these because I won't need the spares for a while. Please feel free to use them if you'd like. Depending on how you wear them, they should fit up to a 25cm foot size.
