Heat resistant silicone band.
Manufactured from a half and half 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 improves biodegradability.
