Us Two Tea’s biodegradable tea sachets are safe for your health and the Earth. Did you know that most tea sachets are made of bleached plastic, which releases toxic chemicals into your tea and the environment? Tea sachets have helped us simplify the traditional process of steeping loose leaf tea, but we have not compromised quality, safety, or taste. Made with corn fiber, our tea sachets are as natural as our tea. Enjoy the pure goodness of tea, and nothing else.
