Surprisingly Sturdy for Disposable Plates!
Color: 9 in 500 White
These plates were purchased as a replacement for the value pack of 500 paper disposable plates. What an amazing difference! I try to avoid unnecessary use of disposable plastic. These COMPOSTABLE plates are thinner than typical cardboard plates and don't absorb the moisture right out of the food! As for durability, these plates rival the name brand heavy duty plastic plates, and they are far better than Styrofoam.

Great plates
Color: 10 in 500 White
Was sick of buying 50 plates at a time from the grocery store all the time. These are durable, not thin or flimsy like most. Even moist food wont leak through. Good stuff
