Water bottle strap cover. I made a cover to prevent the strap from digging into your shoulder. It's reversible. It can be used as a shoulder strap cover for shoulder bags or as a handle cover for eco-bags. Size (outer dimensions) Length 23.5cm x Width 15cm Folded in thirds Length 23.5cm x Width 5cm Inner dimensions 4cm Can be used even with water bottles where the shoulder strap is not removable (see images ③④). Considering the outer dimensions of the plastic parts used for length adjustment attached to the shoulder strap, it can be used for water bottles with a shoulder strap width of up to about 2.5cm (see images ⑥⑤). I have uploaded images for reference showing the cover attached to a water bottle shoulder strap, but this listing is for the shoulder strap cover only. It will be folded in half for shipping, so ironing is recommended upon arrival. Please consider the type of water bottle you have and the width of the shoulder strap. This is a handmade item by an amateur. I make every effort to be careful, but please understand that there may be some slight imperfections, such as distortion, puckering, or misalignment. Thank you for your understanding. m(_ _)
