Sturdy heavy duty plates
Style: 20 Ounces, Size: 150 Count (6 Packs of 25 Bowls)
I have bought these Dixie plates for a few years. They are very good, sturdy plates. I also have the bowls to match. Plates are sturdy and will not bend like regular paper plates

Save Sanity (and Sinks)
Style: 20 Ounces, Size: 56 Count
These 20-ounce bowls have been a lifesaver for a big family with no time—or sanity—to spare for a sink full of dishes.
Don’t fill one with water and leave it overnight unless you’re running a paper-mâché experiment. For hot soup, I’d recommend using two bowls, but for cereal, pasta, snacks, or fruit, they’re perfect.
I even found one that had been left outside in the rain for a few days and it still hadn’t disintegrated—so sturdiness gets bonus points.
Also, three scoops of ice cream plus toppings? Tested and verified.
If you value your peace of mind more than your dish pile, these are the bowls you’re looking for.

These are great
Style: 20 Ounces, Size: 56 Count
These hold my hot and cold foods with no problem. I have not had an issue with leaking and it’s been safe to use in the microwave. I’ve even had liquidy foods in it. Like juices from the food. I have also eaten soups with no issues. Great price and durable.
