I purchased these at the shoe corner on the 2nd floor of Isetan Shinjuku a few years ago, but my fashion taste has changed and I no longer use them. I wore them once for a few hours. The size is 36 1/2, which is 23.5cm in Japanese size. The studs sparkle and are cute every time you walk! Even if any of them come off, there are two spare studs. Comes with a box and a dust bag.
