Love these for the price! Normally I get Walmarts off brand but this is so much better quality and delivery right to my door! Love how sturdy and leakproof they are and ease of use for party friendly events or everyday use; very versatile!

Great value!

Nice paper plates! They’re sturdy enough to hold two fairly heavy sweet potatoes safely in one hand, they have a waxy layer so liquid and gravy don’t soak into the plate. The design is nice. For the price and the quantity alone, I’ll keep ordering these!

Sturdy and good price
Size: 10 Inch, Unit Count: 44
These plates a wide and sturdy. We use them everyday at home to minimize dirty dishes which makes cleaning really easy. We’ve had even stew on them which can be very soupy and they don’t leak and they don’t get soggy. It’s also a good price point for the amount of plates it comes with. Good for everyday use or for hosting as well
