Enjoy better tea flavor with the help from tea filter bags that are eco-friendly and resistant to high temperatures. Tea filter bags are made of strong material with a wide mouth for you to easily fill it up with your favorite loose tea leaves and to seal up with the drawstring. The filter bags act as a teabag, locking up your tea from coming out, yet also giving your tea enough space to expand. But if you so wish, these filter bags are also good for coffee, spices, herbs, bath salts, and much more. These filter bags fit perfectly in a standard sized cup, travel mug, and tea pots.
