GU Sailor Moon Luna flats

Bought these about 10 years ago, when they were released, directly from GU in Tokyo, but have never worn them. I was unsure of Japan's shoe sizing and went with the XL, but they're still too small. I would say if you run 7.5-a smaller 8.5, these will fit. Maybe even a small 9, definitely a narrower foot. They're blue velvet and like new, no box though.
