I purchased these from this site in 2019 and tried them on once, but I wasn't sure if I was doing it right, so I attached and detached the Velcro several times. There's some remaining fuzz, but I think it shouldn't affect use. See photos 4, 5, and 6. I bought two of them together (1400 yen + 1350 yen), and one is unused. The brand was & you (Ange). Feel free to ask any questions! Thank you.
