The main body of the belt is 10mm wide and can accommodate 11mm or more by attaching spare end pieces. Length is 143mm. The price includes the belt and a set of spare end pieces. If you would like spring bars, please comment with the required attachment width and I will include them at no extra charge. Transactions are generally conducted via standard mail, but for those who prefer anonymity, I can switch to Kuroneko Yamato (or postal service if that's more convenient for receiving) for an additional 100 yen. #WatchStraps #11mm #12mm #13mm #14mm #15mm #16mm #17mm
