Thank you for viewing! This is a handmade pet bottle cover made with double gauze. When you buy a drink while you're out or when you carry it frozen, the gauze absorbs the condensation, so you can put it in your bag with peace of mind. It has a hidden gusset, so it becomes flat and doesn't take up much space in your bag. This is for 500-600ml bottles. Size: Approximately 21.5cm (height) x 12cm (width) x 6cm (gusset) The fabric has not been pre-washed, so there is a possibility of slight shrinkage. This is a handmade item by an amateur. Each item is handmade, so there may be slight variations in size and sewing. Please purchase only if you understand and accept the nature of handmade items. * If you select regular mail or non-standard mail, we basically ship from the post office counter, so we cannot ship on weekends and holidays. Thank you for your understanding.
