Good value

They work as well as the big brand name at a better price. They're a little thinner but still strong enough to do the job with no concerns.

Good bowls
Size: 200 Count (Pack of 1,20oz)
These hold up for what I need them to. My child uses them for everything. Have used them for food and cereal. Like that they are good size almost like the plastic ones I have. Put water in them for the cats outside and they held up for a day or so. You get a lot for what u order.
