New Upgrade - Explosion-proof Safety: The fluffy hot water bottle meets the internationally recognized British safety standard for hot water bottles (meaning it is absolutely safe and durable). It is made of environmentally friendly PVC, which is non-toxic, odorless, and harmless. High-temperature and high-pressure molding technology with a large lock nut ensures explosion-proof safety and guarantees no leaks. Soft and Luxurious Cover: This hot water bottle comes with a soft and luxurious faux fur cover. The cover is removable for easy washing. It not only prevents direct skin contact with the hot water bottle to avoid burns, but also retains heat longer. Long-lasting Warmth: The thick PVC hot water bottle with cover effectively slows down heat loss. You can use it for menstrual pain, muscle pain, during pregnancy, or as a foot warmer. These hot water bottles are ideal for cozy and warm evenings! Perfect for cold nights! An excellent gift for women and men.
