Classic 350ml reusable coffee cup which is manufactured from a 5050 blend of natural rice husk fibre and BPA-free polypropylene. Rice husk 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. Other features include a secure screw on lid and a heat-resistant silicone band. A great reminder to you, a family member or friend that you are enough. This is not dishwasher friendly so please hand wash.
