Japanese Wooden Flip Flop Sandals with Mother of Pearl Inlay and rhinestones

These are the most unique shoes I have ever seen. They are black wooden (sealed) flip-flop sandals. There is an extensive amount of mother-of-pearl inlay and gorgeous rhinestones on the straps. No defects and barely any wear. There is no brand and no size any where on the shoe. I am estimating that its a size 6.
