Where are these pans manufactured?

Mine says China on the bottom which bummed me out because I was lead to believe it was Dutch made. Had dutch made tightly whiteys when I was a little kid and they were some tough underware!

Can an egg be fried without sticking in this pan?

First use of the 8” was for a fratatta: eggs, cheese, spinach, ham, mushroom... all added to the cold skillet and baked in a 400F for 30 minutes. Thinking this would be like my cast iron I slipped a knife around the edge to release the fratatta but it was unnecessary. The whole thing slid out perfectly. Quick wipe with a paper towel and done. Amazing skillet!

the product dimensions description does not seemed right. 10"x5"x5"??

My pan's dimensions are 10 1/4" across the rim. 8 1/4 inside the cooking surface and 1 3/4 deep. Still love cooking with it.

This pan, and others like it (OXO, and Merten & Storck) are made in China. They are all basically the same pan. The only real differences are the handles.
