I Put 2 Raw Eggs in This Paper Bowl… (Video Included)
These paper bowls are smaller than standard size, and that’s actually exactly why I buy them. They’re perfect for kids’ snacks and portion control without overfilling or wasting food. I was pleasantly surprised by how sturdy they are. These do not crumple easily like cheaper paper bowls, and they hold their shape well even when handled by kids throughout the day. We regularly use them for dry snacks like Goldfish crackers, cereal, and cookies, and a single bowl can last all afternoon through multiple refills. They are also leak-resistant, which I tested more aggressively than most people probably would. I cracked two raw eggs into one bowl, swirled them around, and set a timer. After a minute, I it held up (over my head) without it bending or collapsing. That alone sold me on the durability. The end result - no leaks. Zero. For the price, quality is excellent. If you’re looking for smaller bowls for snacks, portion control, these are a solid choice. These aren’t your typical flimsy paper bowls — they’re surprisingly durable for everyday use. Kitchen Chaos Tested™ — and they passed. ⭐️I included a video of paper bowls vs raw eggs, plus some photos for size reference

Sturdy and useful
Good plates, we used them all and had no spills or plate disasters. We used them for hot and cold food. Sturdy and saves me time on dishes! I also appreciate that they look nice even if it isn't for company. Great for draining bacon with a paper towel. So much easier. Also, from my home schooling days, these are great for kids when they want to paint. Holds the paint and it is somewhere to lay your brushes.

Perfect smaller size, challenging to separate sometimes
We prefer to use the smaller paper bowls instead of the much larger ones, since they are more in tune with correct portion sizes. The size is perfect, the quality is fairly good, but docked one star because several times when wanting to get one bowl, it’s been a challenge to separate only one bowl. We would probably buy again, but these wouldn’t be our first choice.
