Yunex 10483 Due to a sudden tournament requiring collared wear, and since I usually only wear sleeveless shirts (to avoid them getting in the way during smashes when I sweat), I quickly purchased these items from Australia and China. All are size O, and the white one has been opened and used about 3 times. I would appreciate it if you could purchase them all together, but separate sales are also possible (in which case the price will be slightly higher). I think they were the tournament wear for the Tokyo Olympics.
