This is a shoulder strap! It's a strap with a sturdy back strap and a tape adjuster buckle. Please refer to images 2 and 3 for the size. *The length of the tape adjuster buckle part can be adjusted, but the listed size is measured in the purchased state. Thank you for your understanding. ・I purchased this but didn't use it, so I'm selling it. ・Please note that there may be slight errors due to amateur measurements. ・It is a new, unused item, but it has been stored at home. Thank you for your understanding! #bag strap #strap #bag strap #strap #tape adjuster buckle #adjuster #buckle #handmade accessories #handmade
