This infuser is the perfect size for loose teas because you have the flexibility of using a small amount of tea for a light cup but it is large enough if you want to add more for a heavier flavor.
The mesh is small enough that no tea escapes, and it closes tightly enough that no leaves can leak out the seam either.
A simple clip keeps it closed and the chain is long enough to hook around the mug handle and still have the infuser near the bottom of the cup
Multifunctional, you can mix up a mixture of tea, or put some spices and ginger inside when you are cooking
