This is a set of two watch straps. Both are 23mm. They are not sold separately. All items are used. They became unnecessary after replacing the straps on a watch I own. Professional cleaning has not been performed. Please understand that they are being sold as-is. There are no cuts, hardening, or deterioration. Overall, I think they are in good condition. There are some slight wrinkles and curling, but there are almost no scratches or stains. One strap has no manufacturer's name engraved, and the other has the word "CITIZEN" on the back. How about it for those who have many watches, those who use them for resale or maintenance, or those who resell them individually?
