Great Small Plates
Style: 600 Count (2 Pack of 300), Size: 300 Count (Pack of 2)
I love these plates. I have been buying them for a couple of years and I think they are a great value. I use them to feed my cats and dog, and for reheating leftovers for lunch at work. They are sturdy, don't soak through, and the perfect size for my needs.
I don't understand why people have left negative reviews because they didn't read or comprehend the clearly listed plate size.

They do their job!
Style: 600 Count (2 Pack of 300), Size: 300 Count (Pack of 2)
The thickness and the strength of these plates is great. They’re not flimsy at all. I haven’t had any issue with their functionality since small plates are typically for desserts or snacks. The only issue I’ve had is that they tend to be stuck together a fair amount of the time. Before gatherings, I’ve had to separate the plates. Not a huge problem, just a little inconvenience imo.
