Nylon water bottle cover with a zipper, black and gold color scheme. - Brand: Finecharge - Material: Nylon - Color: Black/Gold - Features: Zippered pocket - Bottom Design: Mesh bottom - Height: Approximately 17.5 cm This is a water bottle cover. I only used the main body, so there are no stains or signs of use. I think it will fit a water bottle with a bottom diameter of about 8 cm. No strap. Although unused, it has been stored at home, so please understand that it is a used item. I will fold it compactly and pack it.
