Width: 3.5 cm Length: 21 cm Dark Brown It's old, but I haven't used it much. I used it a few times a season. There are some scratches because it's leather. There are also creases from storage. The leather is still stiff, so I think you'll be able to enjoy the aging and wear of the leather in the future. The length can be adjusted in two stages with buttons. I measured it, and it's about 18 cm with the inner button and about 19 cm with the outer button. I'm a woman, and it fits just right with the inner button.
