This is a water bottle strap cover. I made this cover to prevent the strap from digging into your shoulder. It can also be used as a shoulder strap cover for shoulder bags. Size (outer dimensions) Length 24cm x Width 5.5cm ☆ Fits water bottle straps up to 4cm wide (see image ④) ☆ Compatible with water bottles with removable straps (see image ⑤) ☆ Quilting fabric is used on the part that touches the shoulder. ☆ I have uploaded images for reference of the cover attached to a water bottle strap, but this listing is for the shoulder strap cover only. It will be folded in half for shipping, so ironing after arrival is recommended. Please consider the type of water bottle and the width of the strap you have. This is a handmade item by an amateur. I try my best to make them carefully, but please understand that there may be slight imperfections such as distortion, puckering, or misalignment. Thank you for your understanding. m(_ _)m
