Question: What is the diameter of the 18-oz. bowls?
Document: I ordered this set of Corelle along with the Corelle lunch plates. The lunch plate box sounded like a bunch of marbles, everything was shattered. The Winter Frost dinner set showed up intact but when I pulled the dishes out of the box my first thought was that they were plastic but they are simply fragile feeling dishes. The bowls that come in the set aren't large enough for a kid's cereal bowl (6 oz.). I sent them back fearing they would end up like the lunch plates.
easy to clean, looks very neat, doesn't break. Wish I could order just plates and pasta bowls. Would love to buy more.
This is a beautiful set. I'm really happy with the bright white color and sturdy feel. I wish the bowls were a little bigger though
These dishes are so light. They are easy to clean. They look beautiful! The bowls look small but are just the right size. I like that it doesn't have coffee cups. I never use the cups anyways.
Very nice dinnerware. Chip resistant and light weight.Bowls are jut the right size. I think Corelle Wareis a good quality product at a very good price.Definitely met my expectations! !
I love that the color is plain white. Very neutral and pairs well with my existing set. I grew up with Corelle ware and don't recall any plates chipping while my ceramic plates and bowls seem to chip quite easily.
This was an excellent find. The dishes are thin, lightweight, practical in size and shape, and durable. After a few months of use we have &#34;tested&#34; the plates and bowls to see if they break and not one has the slightest chip. We have linoleum flooring so i'm not sure how they would fare on something like tile.
The bowls are a bit shallow for my preferences, but I have found they are the perfect size for my two smaller dogs (when I give them a left over treat). Because there are six of each piece, I can load up my dishwasher before running (I do rinse them off before putting in the dishwasher). I have had nothing but good experience with this product.
I am very pleased with this set for everyday use. The plates are light weight and very durable. The salad plates are smaller than I wanted, but I still use for appetizer plates and they work well. They are easy to handle and washes up great. The bowls are the perfect size in my opinion for cereal also.
We had Corelle in the past...don't know why I ever got rid of it. It is absolutely the most practical everyday dish set available. We have big mugs (doesn't everyone?) so just wanted the dessert/bread size plates, larger dinner plates and the cereal bowls. You can't hurt them, they are totally neutral and just the right size. They were delivered very promptly. Love these!
Answer: They are 6" across...perfect for a bowl of cereal!  Unless you like huge portions which we're all trying to get away from!
