[U-shaped hot water bottle with cover]-- This U-shaped water bottle is made of flexible rubber with a fleece cover, making it comfortable to wear. It holds 1 liter of water, but we recommend only filling it 2/3 full. This prevents water from spilling out and allows the water to distribute when in use.

[Heat for pain relief]--Using a hot water bottle or bag for pain relief is a common remedy for relieving neck and shoulder aches. The shape helps you easily mold the bag to where you need it most, treating sore muscles, cramps, arthritis, aches and pains, migraines, stiff neck, lower back pain, menstrual cramps, stress, and minor injury swelling.

[Durable and environmentally friendly]--The bottle is under the safety standard for heat packs for pain, meaning it is leak-proof and durable. The bottle and cover are vegan and safe for children. CAUTION: an adult should always supervise and never fill with boiling water.

[Easy to use]--Wide mouth design, fill the water bottle more easily and reduce the risk of burns. Strong screw cap ensures no water leaks out after tightening. When you are finished using the bottle, empty it completely and store it in a cool, dry, and dark place until you need it again.

[Choice for winter]--Best warm choice for winter travel, camping, hiking, or other outdoor activities, protect your hands or other exposed skin from frostbite. Comes with a soft hot water bag cover to prevent direct skin contact with the hot water bag to cause burns.
