This is a CASIO wristwatch belt, made of stainless steel with a 18mm lug width. The belt's shoulder at the ends is about 21mm wide. It seems suitable for old G-Shock watches. As shown in the 7th photo, there is a slight indentation, so I've marked it as having some scratches and dirt, although there is no dirt. There is no problem with use. Therefore, I'm offering it at a slightly reduced price. There are minor scratches from use. I have cleaned it with ultrasonic cleaning before listing, but please refrain from purchasing if you are looking for new quality. Thank you.
