T-sac filters are a most convenient method for tea preparation. You get all the convenience of a disposable teabag, and they come 100 to the box. This #2 size is perfect for one cup or will hold enough tea for a 2-4 cup teapot. You can staple them shut or just twist the top to keep the tea leaves from escaping. Unbleached, and they won’t interfere with the flavor of your tea.
