This is an underarm sweat-absorbing inner garment. I've used it three times. It feels good against the skin and absorbs sweat well, but I'm selling it because the size didn't fit me. The color is black. The manufacturer's label indicates a length of 23cm, but I measured it just now and it was 21.5cm (see photo 3). The width was also 26.5cm (see photo 4). Please refrain from purchasing if you are concerned, as it has been used.
