AirBake Nonstick 2 Pack Cookie Sheet Set, 14 x 12in and 16 x 14in

The picture is deceiving.. is there a lip around the outside to hold spills?

How do you get the HUGE glued on label off the cookie sheet without scratching the pan?

I found a recipe that called for air-chamber baking sheets. Is this the same type of product?

Are these AirBake? 2) What size are these?
