This is one of the best tools we have found for making tea in a mug or large pot - plenty of room for the leaves to expand and release their flavor.

The permanent micro-fine, stainless steel mesh filter does not affect aroma or taste and filters out even the smallest tea particles. Brewing basket with stainless-steel mesh and heat-tolerant plastic frame. Ample room for the tea leaves to expand. Permanent filter for brewing your premium tea. Taste and aroma uneffected!

Complete with lid which can act as a coaster once the infuser is removed from your mug or pot.  Dishwasher safe.
