Oven safe, Light weight, beautiful, non stick, great quality,  & Perfect sizes.  I love this set! This is the first time in my life that I have not minded frying eggs and actually look forward to it.  A little bit of butter in the pan and the eggs did not stick at all, everyone of the eggs turned out perfect!  After using these for the last week daily I have not found one thing that I do not like about them.  They cook very well and very easy to clean.
