[Good Permeability] No tea leaf particles float out through the bag while allowing the tea to steep properly. [Sturdy Design] The tea bags remain intact when used for brewing coffee or tea in an oven or pressure cooker. [Mess-Free Use] No cleanup required, making it easier than using a metal infuser. [Multiple Uses] These tea bags can be used for bath soaks, soup spices, foot baths, desiccant storage, herb bundles, and more. They can also be filled with carbon to help keep aquarium water clean.
