This lunch box is made of biodegradable, sustainable bamboo. Bamboo is one of the fastest-growing plants in the world - it only takes a year to grow back after it's been harvested. It is a hardy plant, that doesn't need much water or any fertiliser to make it grow and thrive. And it is naturally anti-microbial, which makes it perfect for holding your food and ensuring that you've got the lunch you need to see you through. The lid of this box is made from rolled bamboo, and the base is made from bamboo fibre.
