The Natura Coffee Mug is a 350ml round coffee mug which is manufactured from a 50/50 blend of natural wheat straw fibre and BPA-free polypropylene. Wheat straw is a waste product with little value and the agricultural industry often dispose of it by burning which creates air pollution. Using it to make a reusable coffee cup reduces the amount of plastic and produces a trendy natural look. An optional black gift box is available on request. This product is not dishwasher safe and handwashing is recommended.
