These are Central Sports swim caps, one light blue and one black. Both are size L. I used size M for the navy blue cap, but for the light blue cap, I switched to L because it's made of rubber and harder to put on. It seems to fit perfectly without coming off when diving ★ ※ The inside of the light blue cap is white, so it shows some wear, but it's still usable. ※ The black cap is in very good condition. ※ Both caps have names written on the tags, so I will erase them with a marker before shipping. Thank you for looking (=^・^=)
