Query: Deceptive photo

I ordered these because they were in sheet form. But they came rolled up, which seems to defeat the entire purpose of ordering these rather than rolls.The surface was also very wavy and corrugated which rendered these unusable for my application as opposed to the very flat sheets seen in the product image.I'm sure they're fine for simple baking but for my needs, these were completely unsuitable.
