Design inspired 350ml reusable coffee cup that has an incredible story to tell. It is manufactured from a 50/50 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. It has a heat-resistant silicone band and a secure screw on lid with a splashproof flip closure. This product is not dishwasher safe and handwashing is recommended.
