Very lightweight but good everyday
Size: 500 Count (Pack of 1)
These are great for everyday use. I use them under bowls when I microwave, to collect pieces of food that I’m going to throw away while I’m cooking. Good enough for toast or a microwaved muffin. They are lightweight and not meant for heavy amounts of food.

Consistent quality
Size: 500 Count (Pack of 1)
This is the first time I’ve ordered this online and it is exactly what we have been using for years. We always use a plastic support and the plates themselves are flimsy. Good value. And easy to use. But I wouldn’t trust it to NOT leak.

Great non-toxic option for big families!
Size: 500 Count (Pack of 1)
I purchased these several times. We have a big family and paper plates are just part of our norm right now. I was looking for something that doesn't have forever chemicals lining the plates. These are perfect. You can't carry around the plate. These are for putting on the table and putting food on them :) But that's what we needed them for !

Size: 100 Count (Pack of 1)
Not strong enough to carry food on, but good enough to cover small bowl in microwave to prevent splatters, small enough for toddlers to create with.
