I bought this set of Blue Diamond 12 " fry pan and lid as a gift for my granddaughter-in-law. I also bought a 10" Blue Diamond fry pan.  This is the only cook wear that I have had for several years and  there are no scratch or burn marks on them. If you do not use cooking sprays only butter, oil or margarine, there will be no sticking and easy cleaning.  Blue Diamond cook wear are great pans and I'm so glad I found them 5 years ago. My purchase came well packaged, and even though it is Christmas time, the set came on time.
