Our signature pyramid-shaped, heat- sealed tea bags are made of high-grade Nylon mesh which is food-grade material that meets food safety standards and regulations. It doesn't tear up easily and brews a strong flavorful cup. The pyramid shape allows more room for the tea leaves & ingredients to unfurl, offering a rich and flavorful cup of tea, as against low-grade tea dust used by conventional brands. As a part of our sustainability and environment-friendly initiatives, we are gradually switching towards producing only plant-based pyramid-shaped tea bags. These new and upgraded pyramid-shaped tea bags are plant-based, environmentally sustainable, and entirely plastic-free. The pyramid bag holding the tea leaves and the string are made from natural plant starch.
