It’s never been easier to warm up your child’s bottle when out and about than with the Babymoov Travel Bottle Warmer! A brilliant design that works without having to plug into any electricity or external power source: you simply twist the cap and it will warm up anything inside, and keep it warm.The warmer consists of a PVC heating case filled with a special non-toxic liquid that solidifies when cold and liquifies when warm. So when you twist the cap, it warms up. And when the warmer eventually loses its heat, you can easily reactive it, making it continuously renewable. A large, stylish neoprene isothermic casing preserves heat for longer, and special carrying handle allows you to either carry it or attach to a pushchair or maternity bag and its large size means it’s scalable and capable of warming bottles and jars of various sizes.
