This is an unused, stored rubber strap with a carbon fiber pattern embossed on it, in a black and red color scheme. The original price was 2860 yen. It is compatible with a lug width of 18mm. The following are the dimensions from the purchase page: Tip: 133mm Buckle side: 80mm Thickness: 4mm That's all. I purchased this approximately 7 years ago, when I was deciding whether to put a NATO strap or a rubber strap on a watch I owned at the time. Ultimately, I was satisfied with the NATO strap I received, so I never even put this one on, and it has been stored until now. I'm selling it because it's a waste to keep it. I think it would match active-looking watches, such as divers' watches and digital watches. Thank you.
