Great plates, but a little expensive
Size: 125 Count (Pack of 1), Color: White
These plates are easy to use for just about any meal. They are strong and durable, and they come in various sizes to fit your needs. They’re sturdy and hold plenty of food, without getting soggy or sagging. Their sturdy compostable concept is fabulous, but it seems that it results in the item costing a bit more than I’d expect to spend regularly.

I have been purchasing these plates for over a year and a half to two years and they’re quite excellent. They are very durable and hold up exceptionally well. A great value for the dollar.

These work great for a really good price. I love using these when I'm making dishes that would be difficult to clean otherwise.
