This tea bag is made with whole leaf post-fermented Pu'er tea produced in 1997. The 20 years of ageing allows the tea to develop a gentle, mellow and full texture, and a charming aroma. The original whole tea leaves are packed into bags without chopping. It's convenient to carry and brew, while guarantee the original flavour of the tea. Unlike conventional teabag that can release up to 3 billion nano plastics per brew, our tea bag is made with corn husk fibre, which is completely safe and healthy in hot water. It's also fully compostable, making your tea drinking habit more green and enjoyable.
