Moko Moko Fuwa Fuwa (Fluffy Fluffy) Wristbands Cuffs White I think these can also be used on the ankles. They have elastic so they stretch, but they are a bit narrow. I bought these on SHEIN, but I have an extra one, so I'm selling it unused. Perfect for idol costumes, Nijisanji common costumes, everyday wear, and cosplay! Instant purchase O.K. No price reduction.
