Better than paper plates
Size: 9"
Both convenient and sturdy...great for serving lunch and dinner...the smaller plates are great for dessert or breakfast (toast, muffins, quiche)

Great value and great biodegradable plates for snacks or lods
Size: 6", Size: 6"
These plates were exactly what I was looking for! These 6" plates are smaller ones, so if you need larger ones, then get the 8" ones:)

Great value for very sturdy, leak free plates
Size: 6"
Really like these plates! They had the best price per plate & come in a large quantity which is a huge plus for me.
We use them to feed our cats wet food & sometimes water & the liquids have never leaked through the plates
They are the perfect size for feeding, 1 plate will easily hold a can of cat food.
They are very sturdy & don't slide across the floor while the cats are eating off them.
