I have now purchased five of these Kati cups and I use them every day with both the loose teas and the pyramid infusers. They wash up very nicely, and they are the perfect size for a hearty cup of tea. I love the designs and always have trouble choosing just one!
I love the Kati steeping cups generally. They are very elegantly designed and the exterior stays a comfortable temperature even when filled with hot drinks The Noir cup is great because it is pretty gender neutral whereas my others are a bit more feminine. This is a great product that I would definitely recommend.
The steeping cups are the best. Double-walled, they keep the tea hot and your hand only warm - no burns! If you keep the lid on after removing the infuser, the tea stays hot a long time. Or, use the lid upside-down as a coaster to hold the infuser. I've been giving these as gifts to a number of relatives and have two of my own. A wonderful way to enjoy tea.
