These plates are very convenient for busy days and parties, hold up well with regular meals.
Size: 10inch-140, Size: 10inch-140
I grabbed these for the upcoming summer because we have so many events coming up: graduation party, kids sleepovers, family gatherings and honestly even for those lazy evenings when I am just too tired to deal with dishes. I am actually very happy with them because they hold up much better than many disposable plates I've tried before. The plates feel sturdy enough for regular meals and snacks without immediately bending or getting soggy. One thing I appreciate is that they were even reusable for lighter drier snacks like nuts, crackers or cookies. If the food wasn't greasy or wet, we could easily use the plate a second time which actually helped reduce waste during busy gatherings because i noticed people going around and reusing for multiple foods. My son use them to do a quick warm up in the microwave for a slice of pizza but was only for 30 seconds and it seemed fine so i can say they are microwave safe but for shorter cycle. I love the white background with blue trim details. These are really practical plates to keep stocked up at home considering the great bulk value of 140 plates, very convenient, sturdy and a huge help when you want easier cleanup without constantly washing dishes. Lifesaver! Here is how I rate items: 5 Stars = Exceeds expectations, a good find. 4 Stars = Very good quality, worth trying. 3 Stars = Decent and does what is says. 2 Stars = Below expectations with noticeable issues. 1 Star = Very poor quality, would not recommend.

Sturdy and Elegant: The Perfect Heavy-Duty Plates for Hassle-Free Entertaining.
Size: 10inch-140
Planning large family dinners and outdoor gatherings requires reliable tableware that can handle a full menu without falling apart, and this 140-pack of 10-inch paper plates from BYSNOW is an exceptional choice. Featuring a beautiful blue leaf pattern, these plates bring a refined look to the table while delivering the structural strength needed for heavy entrees. They are also microwave safe. I used these for a recent family gathering, and they held up perfectly from appetizers through the main course. The quality of the thickened cardboard construction is impressive. These plates are incredibly sturdy and do not bend, warp, or collapse under the weight of substantial foods like grilled steaks, pasta, or loaded burgers. They are engineered with an upgraded leak-proof surface that handles moisture and oils seamlessly, preventing any sogginess or tearing even when guests are using sharp utensils. With 140 pieces in the bulk pack, it is incredibly convenient to have a steady supply on hand for picnics, barbecues, and celebrations without the need for constant restocking. Cleaning up after an event is entirely effortless since they can be disposed of right away, saving valuable time that would otherwise be spent washing dishes. For any host looking for a combination of durability, aesthetic appeal, and convenience, this heavy-duty plate set offers fantastic value and performance.

Close, but not quite as strong
Size: 10inch-140, Size: 10inch-140
These plates are very similar to the name brand that they look like. However the paper is slightly thinner, so for many things these act similarly, but for heavier things I found them to need more support from my hand because they flex a bit more. If I was using them for a party with heavy food I would definitely use paper plate holders with them. They seem to have the same coating to make them soak proof and that is a plus when I use them for food that's more moist or greasy. I find them fine for everyday use and the design is pleasant enough to look at. I will definitely check the pricing before buying to make sure it compares favorably given the slightly lesser strength.

Strong with high rim, makes for a great disposable plate
Size: 10inch-140
I really like these paper plates because the rim is so high. It’s definitely higher than many other plates that I’ve encountered. This helps food stay on the plate, no matter who is using it. The plates are super sturdy too. I can put heavy, wet foods on it (like a can of dog food) and hold it with one hand without it buckling or collapsing. The paper is thick, which helps add to the sturdy feel. The design is super basic. They are white with a simple design adorning the rim. They look like regular paper plates you might find at the grocery store.. except these are stronger. I think they’re a great value. I love using paper plates, since I don’t have a dishwasher. I often use them for my dogs wet food. The rim is high enough to keep all of the food on the plate, despite him moving it around a bit. The plate size is great too. They’re large enough to use as a dinner plate in my household. I’m happier with thee plates than I expected to be. I’ll take a super functional plate with a plain design over a “pretty” plate that flops in half when you carry food on it. Function over aesthetics for the win.
