Everybody has their own sense of style. Which is why we offer our Corelle dinnerware in so many different patterns and shapes. But one thing everybody agrees on is durability. Dinnerware needs to last. We use a unique material called Vitrelle , which gives our plates and bowls that legendary Corelle durability. It also gives them a number of other benefits that other brands can't offer. Our glass dinnerware is designed to make an impact and take one.
