The light and delicate pure green tea, with a bright golden colour, tastes as good as it looks in the cup. Plastic-free tea bags* *Bags More to Feel Good About: These tea bags are sealed with PLA which is a bio-polymer made from a renewable, natural and non-GM plant source. They are completely free of plastic made from fossil fuel, such as polypropylene. This is the plastic that's left behind when normal tea bags break down. You can pop our tea bags into your food waste bin and they will fully biodegrade.
