The design of the set makes sense with 2 kinds of very functional bowls as well as the roll plates and the dinner plates. The set lacks coffee mugs which is good, who doesn’t already have a cupboard full of those,  but a couple of caveats:
The dinner plates are a little on the smallish size (another inch or inch and a half would make a difference) and the beautiful spiral design is marred somewhat by a weird random distribution of black spots like you get when you shake a pen and it sprays spots of ink on something. Some plates have just a little, some have more but why have any at all?
