All you need. It is literally all you need to make a superb cup of tea to enjoy at your leisure. On your time, because the double wall glass construction keeps the tea hot much longer than teacup or mug. The lid, which maintains optimal brewing temperature, is the perfect size to rest the infuser once the tea is brewed.
The brewing basket is rigid stainless steel, large enough that the leaves aren’t crowded and designed to allow free water access for precision infusion.
This is such a modern take on classic traditional design. An elegant mug in borosilicate glass with handle and with the double wall construction, keeps tea hot for prolonged tea sipping nirvana.
If you could only have one cup/pot/brewer/warmer combination, this is the one.
