An environmentally-safe and convenient alternative for perfectly brewing loose leaf teas or herbs. No holder needed. Made with chlorine free, unbleached filter paper from manilla hemp. Easy to fill bags have a longer flap on one side to close the bag. A channel in the base allows it to expand with the tea leaves. The size 2 will hold from 1- 4 teaspoonfuls of tea, appropriate for use in a cup or a small tea pot. We encourage you to compost your used tea filled t-sacs. Made in Germany.
