Unless you're trying to eat a whole meal in them, I suggest you buy.
Size: 12oz - 500 Count, Color: White
Good quality for the price you're paying. Some of the bowls crack a little easily, but they hold up pretty nicely overall. From hot soups to ice cream and cereal or a nice bowl of wet food for your pet. They're a good size for a serving and don't wilt quickly when holding any liquids. And they compost, so it's good wn the carbon footprint since I can use them instead of seeking out cardboard for my garden compost.

So many for so cheap.
Size: 12oz - 500 Count, Color: White
So apparently I’m not great at estimating what 12 ounces really looks like in a bowl. Therefore they were smaller than I was expecting, but since I’m lazy and hate to do dishes, they are perfect for our household. Too small is better than too large in my book , as we have no problem with going back for seconds, which these bowls will definitely hold up for. They are leak proof and a great value for how many you get. The thickness it about what you’d expect although the lip seems slightly thin and bends easily when trying to separate them, which isn’t difficult, but not simple by any means. Again not a deal breaker for our house.

Great product
Size: 12oz - 500 Count, Color: White
These bowls and plates are awesome! We love that they are compostable when we are home but we also use them camping and love that they don’t have the waxy coating so we can throw them in the solo stove and they burn clean. They are also strong and can easily hold a heavy amount of food.

I like these bowls. Perfect size for serving a crowd.
Size: 12oz - 500 Count, Color: White
This is an incredible value. Tons of bowls. They are very sturdy. I have to double them if I serve soup.
