【Soft Touch & Improved Cover】The cover for the IZTOSS hot water bottle is fluffy and smooth! The artificial rabbit fur fabric, which you'll want to rub your cheek against, doesn't prick and feels great! It has excellent heat retention, so the warmth of the hot water bottle lasts a long time. The improved cover has an opening in the middle, allowing you to insert the hot water bottle directly. It's also removable and hand-washable, so you can wash the cover and keep it clean even if it gets dirty.
