These are kids' ankle socks purchased at AEON. They are a set of three: pink, purple, and light blue. Only the pink one is different, with a smiley face. They are unused, but the tags have been removed, so please be aware of this. Thank you. The size should be 19-22cm. Photos 6 and 7 show them laid flat with a measuring tape. Please also read my profile. Feel free to ask any questions.
