I’m made of biodegradable rubber which means that over time I will degrade and be ready to go back to mother earth. So please regularly check me before filling me up. Thanks!

If used and stored according to recommendations, your hot water bottle should give good service for approximately 2 years; during this time, rubber will naturally deteriorate, therefore it is advisable to replace your hot water bottle to ensure it is compliant with British standards for safe use.

The YUYU Bottle is made of high grade natural rubber. Use a damp cloth to keep your bottle clean and dirt free. When not in use, drain completely and store with stopper removed, in a cool, dry, dark place. We recommend hanging the bottle upside down with the stopper off so that the bottle becomes completely dry inside.The bottle should be kept away from direct exposure to sunlight. Sunlight can discolour the bottle and harm the rubber, ageing and degrading it. Do not place anything on top of the bottle during storage. Keep bottle fully extended. Keeping the bottle bent will create a crease in the rubber which will weaken it. Please be aware that in areas with harder water, the rubber can degrade more quickly, so it is important to check your bottle before each use.

Cold use: Continuous freezing and heating of the rubber, especially in hard water areas may reduce the lifespan of the natural bottle. For this reason, we recommend using one bottle for freezing and one for heating.

There is a two year manufacturers warranty. We recommend purchasing a new bottle after 2 years of use.
