Great Value & Eco-Friendly!
Color: Brown, Size: 9inch
I love these paper plates! They’re sturdy, affordable, and perfect for everyday use. I actually have them on an auto subscription every two weeks because we use them so often. I also love that they’re biodegradable, which makes them an even better choice for our family. Definitely a great value for the price!

Great quality. 6” plate. 4.5” eating surface
Color: Brown, Size: 6inch, Color: Brown, Size: 6inch
Love the quality. No waxy feeling, ,but has a slight seal on a cardboard plate so food does not make plate soggy. I give a 4 star because, the actual surface that is usable for food is 4.5”. This can be a nice thing as the edge holds food / snack on plate.. Reasonably priced for 100 small plates. Would I buy again maybe.
