Good quality, good buy.
Size: 300 Count (Pack of 1,8.375 Inch)
I liked these plates more than I thought I would. The plates hold up well under load and don’t soak through like regular less expensive plates. The size is right for most meals and still not too big for just dessert. They worked great in the microwave and were easy to separate from the stack. These came packed in a box with two stacks that were each wrapped in plastic to keep them clean in shipping and storage. I will buy these again.

Very sturdy material, easy to separate even for a child. The only clean up is when someone bumps into your plate lol. Great price for the quantity.

Not flimsy

These paper plates are sturdy and hold food well without bending or leaking. I originally thought they were going to be a little bigger than they are, but I still ended up keeping them and using them regularly. They work great for snacks, lighter meals, and everyday use. The quality is good, they’re easy to store, and the large pack is very convenient.
