[Eco-Friendly Material] The UV sterilized tea bags are made of wood pulp paper, sealed by heat press, no glue, odorless, biodegradable and compostable. [Excellent Permeability] No tea leaf particulates floating out through the bag while allowing the tea to steep perfectly. [Sturdy to Cook] The tea bags won't fall apart when used to brew coffee or tea in a microwave oven or pressure cooker. [Mess-Free] No need to clean up, making brewing much easier than using a metal infuser. [Multiple Usages] The tea bags can be used for bath soaks, soup spices, foot baths, desiccant storage, camphor ball storage and more. They can also be filled with carbon to help keep water in tanks clean.
