Love these plates for every soy. I normally use paper plates for lunch but I started using them for non messy dinners. We have even used them for spaghetti. They handled the sauce and meaball and sausage with no problem. I would normally U.S. China plates for something like the, I got lazy one night and used these I was pleasantly shocked they worked with no leak through.

Sturdy plates

I purchased these but I normally go to Sam’s Club for bulk. I had a party and these were a hit. Very sturdy and plenty of room. I don’t really like the edges, they’re straight but that’s cosmetic preference not function.
