The odd size requires two of them placed with an overlap on a standard full-sized cookie sheet. Also, the crease in each sheet caused them to not sit fully flat. The least desirable quality is that they are more permeable than any other parchment paper I've used, so grease bleeds right through them onto the cookie sheet.

Very convenient and easy to use. Wish that the sheets were a little bigger.

Box was damaged and it was quite a mess

Convenient pre-cut sheets, less waste. I use them a lot for my air fryer oven

Great for baking. I prefer parchment paper over foil for baking and roasting

These papers are so convient and are easy to use. No fighting the paper to lay flat.

Ease of use with precut sheets

Perfect size for a medium cookie sheet

These are great for my hubby who can't figure out the roll of parchment paper !

This has saved me so much time I cannot even tell you.
