This is a set of 6 pairs of socks. The top 3 pairs in the photo are thin, and the bottom 3 pairs are thick, winter socks. The thin socks are size 22-24cm. The thick socks are size 23-25cm. The light blue socks have a price sticker residue on the tag. These are new and unused, but they are pre-owned items that have been stored at home, so thank you for your understanding. Immediate purchase is welcome! Thank you.
