- Elastic, spring-loaded mesh opens with light pressure to load loose tea, then releases to close. This keeps the tea contained while you prepare it and prevents spills. - The stainless steel mesh infuser reduces leaf fragments in the teapot and allows water to pass through the leaves while keeping most of them out of your cup. - Made from 304 stainless steel, the tea filter is easy to clean and dry after use. The fine filter is dishwasher safe and reusable, providing long lasting performance. - Simple to use with loose tea like a spoon. The small holes minimize tea residue in your cup and help prepare a smooth brew. It can also be used with coffee, but do not use this strainer with finely ground coffee. - Compatible with a wide range of vessels, fitting most cups and bowls for convenient use at home, in the office, or on the go. Use scenarios: - In a standard mug: open the net, add loose tea, release to close, pour hot water, and steep. Lift and remove the infuser when your tea reaches the desired strength. - In a teapot or cup with a rim: place the infuser inside or across the top to act as a filter while you pour. - With coffee: suitable for certain types of coffee grounds that are not finely ground; avoid finely ground coffee to prevent clogging.
