A heavy water bottle can make your shoulder hurt, right? I've made water bottle strap covers to ease the pain a little. Since they come in a set of 4, they're also recommended for spares or for use by siblings(^^) They are made by combining oxford fabric and quilted fabric, and fastened with snap fasteners. My own child has been using these for many years. They are reversible, so please change them to match your mood of the day(^^) Size 10.5cm x 25.5cm (when spread out) 4cm x 25.5cm (when closed) My family uses water bottle covers with straps about 2cm wide. ⚠ Please handle the snap fasteners gently by holding the button part when opening and closing. Although I make them carefully, they are handmade, so there may be slight size errors, uneven stitching, and double stitching. Please understand this before purchasing.
