The three-in-one warm water bottle is suitable for shoulders, neck, abdomen, knees, and beds. Winter gift: The warm water bottle's hot compresses can promote blood circulation, relieve menstrual cramps, and help you feel relaxed during special moments. Warm water bottles can be used all year round and are the best gift for family and friends during holidays.
