Bamboo Breath 18mm Easy Click Specification

Purchased unused last year and used 4-5 times. It's easy-click, so it can be attached without tools. I believe the condition is still good.
◆Size: 21cm at longest, 18mm lug width, 18mm strap width
(Please allow for slight errors as these are amateur measurements)
◆Material: Stainless steel silver

Thank you for your consideration.
