Water bottle strap cover. I made a cover to prevent the strap from digging into your shoulder. It's reversible. It can also be used as a shoulder strap cover for shoulder bags or a handle cover for eco-bags. Size (outer dimensions) Length 23cm x Width 14.5cm Folded in three Length 23cm x Width 5cm Inner dimension 4cm Can be used even with water bottles where the strap is not removable (see images ③④). Considering the outer dimensions of the plastic parts used for length adjustment on the strap, it can be used for water bottles with a strap width of up to about 2.5cm (see images ⑤⑥). I have uploaded images for reference showing the cover attached to a water bottle strap, but this listing is for the strap cover only. It will be folded in two for shipping, so ironing is recommended upon arrival. Please consider the type of water bottle you have and the width of the strap. This is a handmade item by an amateur. I make every effort to be careful, but please understand that there may be slight distortions, puckering, or misalignment. Thank you for your understanding. m(_ _)
