This is a penguin-patterned pet bottle case. By covering your pet bottle, it absorbs condensation and prevents your bag from getting wet. When the contents are empty, you can fold it flat for compact storage in your bag. Since there are no metal fittings, you can wash it repeatedly. You can keep it clean throughout the year. It can also hold a water bottle. It's popular with elementary and junior high school students because it doesn't touch the floor when hung on a school desk hook. Water bottle not included.
