I'd had Corelle dishes for 25+ years. The designed plates that I used every day were getting pitted I guess I'd say on the edges from the dishwasher. My plain white pieces that I didn't use as much were still good and didn't want the expense of getting a whole new set. I was thrilled to find the open stock pieces on this site and so was able to get new pieces/design while still using the pieces that were still looking good! Great find.
