Thank you for viewing! Starbucks Starbucks Pet Bottle Covers, set of 2, for 480-600ml bottles. Colors: Black and Gray, 2 pieces High-quality, stretchy material The fabric covers are durable and can be used for a long time. ★ There is an air hole at the bottom of the cover for ventilation. When inserting a pet bottle or water bottle, it can be difficult to insert without an air hole, so there is a 5mm air hole at the bottom to make it easier to insert. This is not a defect. Please understand. Please note that there may be wrinkles, fraying, or odors due to being an overseas product. The black and gray fabrics are different, so the sizes are slightly different.
