Men's innerwear, set of 2. First photo: Brass 3°C heat-generating innerwear. Size: M. Long sleeves. Second photo: Air Merry ANGLE innerwear. Size: L. 100% cotton, long sleeves. Both are unused, but the Air Merry has yellowing around the neckline due to age, but otherwise, I think there are no problems. I think it would be good to wash it once. The Air Merry is also quite expensive (purchased for around 4000 yen) and feels warm to the touch. However, there are noticeable flaws, so please understand this before purchasing.
