Thank you for looking! This is a finished handmade water bottle cover. If you like it, you can purchase it immediately. The size is perfect for water bottles with a bottom diameter of 7.8 cm. It is made to fit Thermos 600ml water bottles. It may also fit Skater, Zojirushi, or Tiger water bottles depending on the model number. The length of the cover is approximately 16.3 cm. Please check if the size fits your water bottle before considering a purchase. The color of the outer fabric is off-white. The shoulder strap is made of PP tape, which is resistant to water and friction, and has an adjuster that extends from approximately 55 cm to 110 cm. When fully extended, adults can also wear it. The bottom is round, so it is less likely to get scuffed at the corners compared to gusseted bags. The inside is quilted to protect the water bottle. It will protect against dents and scratches even if the water bottle is dropped. It has been pre-washed, so there is no shrinkage after washing, and it is also durable for washing. This is a handmade item made by an amateur. There may be some unevenness or double stitching, so please only purchase if you understand that it is a handmade item.
