These convenient tea filters are perfect for brewing loose leaf tea, keeping your leaves separate from the liquid while still allowing them room to expand and unfurl. Just fill a sack with a teaspoon of your favorite tea and drop the sac into a cup of hot water, just as you would a tea bag. Each box of T-Sacs comes with 100 individual filters. Biodegradable and disposable, they are ideal for on-the-go tea enjoyment or for brewing one cup at a time.
