Washable quality paper plates
Style: 10 Inch, Size: 150 Count (Pack of 1)
We've used these paper plates for years for all kinds of things and find them to be really sturdy and washable. With a pleasant design that fits any decor, they are wonderful for everyday use. I really like the fact that the top surface can be lightly washed and the plates reused. They come in a package of 150 and are really good value for the money.

An elegant workhorse!
Style: 10 Inch, Size: 150 Count (Pack of 1)
I hate washing dishes so I use these Dixie plates a lot and they are STURDY. They will carry a whole meal without wilting. The rim is deep enough that, should you be so inclined, you could eat ice cream out of them without any dripping or drooping worries. So something like spaghetti or lasagna would be easily handled. I now buy them 150 at a time because they're so handy and that way more economical. I use them instead of a cutting board sometimes. And they just feel the right weight, not too heavy, not too light. For a picnic or a walking-around party they would be the best for preventing spills. But what I enjoy is their versatility. You can even rinse them off and use them again if they've had light use. And the current pattern is cheerful too!!

Sturdy, Convenient Paper Plates That Hold Up Well
Style: Modern, Size: 90 Count (Pack of 1)
These Dixie medium paper plates are perfect for everyday use. They’re strong enough to handle full meals without bending or leaking, even with heavier or saucy foods.
The 8.5-inch size is just right not too big, not too small great for lunch, snacks, or light dinners. I also like that they hold up well in the microwave, which makes reheating easy and mess-free.
Super convenient for busy days, gatherings, or when you just don’t feel like doing dishes. Reliable quality and very practical to keep on hand.

Dixie is the best and bestest price on Amazon!!
Style: Modern, Size: 90 Count (Pack of 1)
Excellent made plates and they stand true to their description. Dixie plates hold up strong to your food . I find there are no leaks coming from the bottom , or soggy , sagging , collapsing cardboard like others. They hold up great in a microwave too. Load on the sauce or gravy and know that Dixie will take care of your food plate. The price is excellent on Amazon as well !! It’s an excellent buy for a fantastic paper plate!!!
