3. Lovely Protective Cover - Comes with a soft, removable knitted cover that helps insulate hot water and maintain its effectiveness for 6-8 hours. It also protects the hot water bottle from bumps and dirt and makes your hot water bottle last longer. The beautiful and charming pattern on the cover makes the hot water bottle a thoughtful and comfortable gift for mothers, fathers, children, friends, on Mother's Day, Thanksgiving, Christmas, and New Year's Day.
4. Easy to use - let the boiling water cool slightly before pouring (do not use boiling water). Hold the hot water bottle by the neck. Slowly add water until 2/3 full. Slowly squeeze out trapped air and tighten the nut. Make sure there are no leaks before use. Package includes: 1 rubber hot water bottle, 1 soft knitted sleeve.
5. Note: It is recommended not to touch the skin directly after the hot water has been injected, to avoid burns, and it is safe to use at an appropriate temperature.
