As with Tea-Pots, one requires a specific mug for different teas .. That's my logic to buy more…. The Tea Sets / Tea-Pots remain undistinguished. When I visited the store, she only had two different types in stock, Models 001 and 009 .. so they made the trip home. Workmanship, finish and overall quality rates good, as does ergonomics. Aesthetics: to each their own, I like them.
I scanned the catalogue and you will note numbers 004 and 014 are omitted. (not by accident, unlucky numbers)
