Back in early 70's when I first got married, I had the plain frosted white set. Don't know what happened to those but just in the past year I decided to go back to the plain frosted white as they don't weight as much as the iron stone set I used to used. My sister also has the same frosted white so while I was collecting some of the extra pieces, if I got more than I needed, I gave the extras to my sister. We're both in our 70's now so less weigh is good.
Though the disclaimer says they won't break if you drop them, I beg to differ as it all depends on what part of the dish lands on the floor as I did have one literally shatter on me years ago. Of course that's a once in a lifetime incident so I don't feel their disclaimer is false. I love my frosted white dishes.
