Our classic molded rubber hot water bottle is just like the one you remember, but it's been updated and improved. In our opinion, no home should be without hot water bottles. It's versatile and has many uses, from providing warmth to easing swelling. Extra-fine ribbing on one side provides gentler heat and prevents burns. Made of natural rubber, with no seams so there is no leakage. Includes a hard plastic stopper. Holds approx. 2 liters. Hanging hole at each end. 13"L x 8"W, 1 lb. Made in Germany. Tip for filling: if using a cozy (not included), place the water bottle inside the cozy BEFORE filling the bottle with water.
