• High-quality material: The hot water bottle is made of high-quality natural rubber, while the covers and belts are made of soft plush fabric. • Leak-proof design: Includes 3 hot water bags with screw caps that prevent leaks and reduce the risk of burns. The cover is removable and washable. It is recommended not to fill with boiling water directly and to keep the water temperature below 80 degrees Celsius, filling only two-thirds of the capacity. • Comfortable waist cover: Equipped with an extra-long plush cover and a double-insert pocket to keep your hands and waist warm. The cover prevents direct heat contact with the skin and helps maintain the bottle's temperature. • Heat and cold therapy: Ideal for winter, providing a warm bed. It can also be used to relieve muscle pain, stress, migraines, cramps, arthritis, neck pain, and stiffness. In summer, it can be filled with cold water for a refreshing touch. • Perfect gift: With a fun rabbit design, the rabbit's ears are detachable and can be used as a toy. It is a great companion for you and your family, adding fun and warmth in winter.
