Thank you for viewing! This is a water bottle cover. The size is made to fit a water bottle with a diameter of 6.5cm and a height of approximately 17.5cm. (Please allow for some error.) The water bottle in the photo is a Thermos 500ml. The shoulder strap is adjustable. I can also make different sizes, so please feel free to contact me (*ˊ˘ˋ*) I can also make items that have been sold in the past if I have the fabric in stock, so please feel free to contact me (^-^) ☆ I may be slow to respond due to work and childcare. Thank you for your understanding. ☆ Immediate purchase is welcome. Please let me know the height of the person who will be using it when you purchase. ☆ This is a handmade item by an amateur.
