Used Windy headgear. I was using this until recently, but I haven't been going to the gym lately, so I'm selling it. As for the issues, the sponge on the round part covering the right ear has hardened and become like sand due to aging. The part that touches the ear (inside) has not hardened, so I don't remember it hurting when I was hit. The size is M, although the tag is faded. Please judge the condition and scratches from the images. It wasn't the main headgear I used, so there's almost no odor, but it is used, so please refrain from purchasing if you are concerned. Returns, refunds, and cancellations are not accepted, so please consider carefully before purchasing. Please comment if you have any questions. Please understand that I will not cancel the order even if you ask questions after purchasing.
