I made a tote bag and shoulder bag shoulder straps (adjustable length) from Oshima Tsumugi silk. The hardware is larger than the smartphone shoulder strap hardware listed on another page, and the width is also slightly larger. Authentic Oshima Tsumugi 9-mark Kasumi pattern Width 1.6cm x Length 70-128cm All hardware is brand new and unused. Due to the increase in the cost of materials, I will have to raise the price slightly. Thank you for your understanding. Thank you very much.
