The tea leaf infuser is the cutest functional way to make a single cup of tea at a time. It works like a reusable tea bag. You put the amount of tea for your cup in the stainless strainer part and close it with the silicone leaf top. It will doddle around your cup until finished steeping. The strainer comes with a coaster to help eliminate a mess when removing your strainer from the cup. Use it over and over for a nice cup of tea.
