Premium quality German made Fashy hot water bottles are made from high grade thermoplastic which means they are odourless, latex free and recyclable. The wide opening (29mm) and large funnel means they are very easy and much safer to fill; and the jointless neck prevents leakages, making them one of the safest hot water bottles on the market. Fashy hot water bottles come with a 2 year manufacturer's warranty and recommended replacement after 5 years (rubber/latex bottles should be replaced every 1-2 years as they start to deteriorate and risk leaking). All covers are Oeko-Tex tested and certified to be clear of any harmful substances to ensure it is a safe and eco friendly product for all members of the family.
