HOT WATER BOTTLE, 熱水袋
RANDOM DESIGN
It is made from natural rubber.  Retains heat for an extra long time.  Ribbed outer surface helps maintain liquid temperature.
Hot water bottle can be used alone as a remedy for aches, pains and sports injuries. In addition to the traditional hot therapy, it can also double up as a cold compress for kids with fever or to reduce swelling for minor injuries.
Practicality:  The temperature of the hot water bottle can be kept at least about 3 hours under normal temperature.  When it is placed in the bed for ten minutes, the bed will warm.  Put it in the quilt and its temperature can be saved all night. Let the hot water bottle warm your winter.
Multi-scenario use:  Can be used for warm hands, warm neck, warm waist, warm back and so on. It can provide you with a warm bed after you put the hot water bottle in the bed shortly before going to bed. It is also a perfect gift!
Easy to use - simply add hot water inside, and securely close tight. Be cautious of hot water!
