Good quality, but too expensive.
Color: Pathways Design, Size: 10 in
Very good quality. Sturdy. Holds up with heavy, hot food. Food doesn't soak through. The only reason I took off one star is the cost. Way too expensive for paper plates.

Great small soup bowls!
I bought these for a family party for soup. I was nervous they were going to be flimsy and cheap. I was pleasantly surprised how thick and sturdy they are! They were a perfect size for a smaller bowl of soup or chili. We even used them in the microwave for left overs and they held up great! There was no sagging or getting soggy which I was also worried about. They are definitely good quality. They are much better than the Walmart or cheap off brands. I also loved the price. I thought they were a great deal for the quality and quantity. The only con I had was some were hard to pull apart. It was no big deal though. I will definitely buy them again.

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
