Thank you for viewing! The bag is labeled as 42/44/45/49mm! When I measure the band, the longer side is about 11cm, and the shorter side is about 9cm. * Although the size is measured and written on the device, I am an amateur, so please confirm the size of your own device and purchase after checking the photos. Since this is a one-of-a-kind item, we do not accept exchanges for confirmation errors or size differences. * Immediate purchase is welcome, and silent purchases late at night are OK ◎ * First come, first served for the only one item * Free shipping! * Please confirm any unclear points before purchasing. * It has been opened for photography, so it is considered as "like new"!
