FAIR ZONE hot water bottle heart

 
The beautiful heart-shaped hot water bottle made of natural rubber gives you soothing warmth on cold nights. With heart lamellae on both sides, the lamellae give off the heat more slowly and more yieldingly.

Application: Heat water in a kettle. But please do not use boiling hot water, even hot tap water can cause scalding. Slowly fill the hot water bottle 2/3 full with the heated water. Hold the hot water bottle vertically at the neck of the bottle so that the water does not splash back. Do not overfill the hot water bottle, as this may cause it to burst. Slowly and carefully let the air remaining in the hot water bottle escape and tighten the screw cap firmly, but not too tightly. 
Note: Avoid contact with hot, pointed or sharp surfaces, oil, grease and sunlight and do not place any objects on the hot water bottle. Under no circumstances use hot water bottle as a pillow or sit on it. After use, store the completely empty hot water bottle in a cool, dry and dark place.
