No extra Cleanup!
Best paper plates. The other plates don’t hold food, they break down and spill your food. Dixie does not. Little more expensive, but worth it. You save money on cleanup..

Tough Plate
These are great dishes for the size! They fit perfectly in our small microwave, are highly grease-resistant, and hold up to several heating's without falling apart.
