This is a set of two shoulder strap covers for water bottles, with removable straps. ■ Size Length: Approximately 23-24 cm Width: Approximately 5 cm Strap insertion opening: Approximately 4-4.5 cm *Please allow for slight variations. ■ Material Cotton fabric The part that rests on the shoulder is made with two layers of quilted fabric, which should significantly reduce shoulder strain. These are not mass-produced items, so please purchase only if you can accept slight imperfections such as warping, misalignment, and double stitching, and if you understand the nature of handmade items. Please carefully examine the images, especially the curved areas, to ensure you are satisfied with the finish (asymmetry may occur). The opening used to turn the cover right-side-out is closed with the final stitch, without hand stitching (see image 3). *These water bottle shoulder strap covers are made using fabric scraps and are offered at a low price. Therefore, there may be individual differences in length (the width is mostly the same). Please be aware of this if purchasing multiple sets. The sizes of the two covers may vary slightly.
