The perfect way to keep your lunch, dinner or snacks at the temperature you want when at work, on a hike or travelling. The silver lining acts as a barrier to oxygen and air which helps to maintain the temperature of the food, be it warm or cold. Made of 100% recycled materials (one water bottle, to be exact), this is a wonderful product that helps fight against our throwaway culture. Designed in the UK, made in China. 7"x12" with grosgrain handles.
