This is a glass mug with an infuser that makes it easy to brew loose-leaf tea.

Open the lid, put in an appropriate amount of tea leaves, pour hot water, and brew the tea.
It is made of glass, so you can adjust the strength by looking at the water color.
Remove the infuser before drinking the brewed tea.
The mug lid can be used as an infuser holder.
