You can enjoy loose tea anywhere with these convenient disposable unbleached, chlorine free paper bags. These easy-to-fill bags have a longer flap on one side. This helps close the bag, or you can trap the top of the bag under a teapot or travel mug lid and close it tight. The loose tea has plenty of room to expand and release its flavor. They are available in two sizes, 100 disposable bags or 50 disposable bags and are similar in size to a #2 and #3 T-Sac tea filter. These compostable, all natural filters are packaged in a bio-degradable clear pla bag (poly lactic acid, a polymer derived from natural starches).
