Thank you for viewing! This is a handmade water bottle cover. Perfect for 500-600ml water bottles. It doesn't take up much space in your bag, and the opening is left uncovered so you can easily remove the cap and drink directly from the bottle. I've kept it simple. A D-ring is attached in one place, so you can add your favorite charms! ★ Charms in the image are not included. Purple x Green, a very popular color combination. Outer fabric: Polyester, Cotton Lining: 4-layer structure, specially processed cold/warm sheet Washable. Hand washing or using a laundry net is recommended. This is handmade. I make each one with care, but there may be slight variations or imperfections. If you are concerned about the details, please refrain from purchasing. Thank you for your consideration.
