These bone china bowls are thinner than porcelain, but are not the very thin and translucent china of fine formal china. I have a similar weight set of every day, dishwasher-safe bone china plates, which I wanted to match.
The color is bone china white, and very lovely.
I received 7" bowls, although the description refers to 6" bowls. Since they are flared, I don't mind, as the capacity is smaller than with, say, a 7" noodle bowl.
The bowls were well packed.
