    Great for 8 oz cups, don't leak
    This is a big pack of cups. The cups are sturdy paper, and they don’t crush easily when held in the hand. They don’t seem to be coated with wax, but they still endure quite well. I left a cup sitting out overnight with water in it, and it didn’t soak through or leak. That is just over 6 cents per cup. These are 8 ounce cups, which is a moderate size. If you were throwing a party for adults, they would need to get refills often. These are perfect size for kids. The cups come in 6 plastic sleeves, that are each closed with a twist tie. The plastic they are wrapped in is pretty sturdy, and won’t rip easily, unlike the plastic sleeves that some cups come in. It’s convenient that you can unwrap only what you need at a time. These cups are a reasonable price, currently priced at $19.99, on Amazon, for 300 cups, in July of 2024. That is just over 6 cents per cup. These are a good quality cup for a reasonable price, just keep in mind that the cups are pretty small for adults.

    Sturdy & worth it
    These plates are super sturdy and reliable! I’ve used them for parties and everyday meals, and they hold up really well—even with heavier or messy food. They don’t get soggy or bend easily, which is a huge plus. Makes cleanup so much easier without worrying about spills. Definitely a go-to for gatherings or busy days!

    perfect size
    purchased for entertaining when I need convenience and quantity. good for larger gatherings- they look good, hold a lot of food without leaking. Strong enough to carry loaded with food without sagging, thick enough to cut meat and not cut through the plate. Can warm up food in microwave and not worry. After the party just toss in the garbage for easy clean up. I will continue to buy these plates.

    Nice Platters for family Thanksgiving take out
    The family used these to take some Thanksgiving food home. These paper platters are sturdy and hold food without bending or leaking. I like the size because it works well for bigger meals or when I don’t feel like washing dishes. They make serving and cleanup quick and simple.

    Perfect for Thanksgiving and Christmas
    These platters are sturdy and just the right size if you’re having a Thanksgiving or Christmas dinner and don’t want to deal with a bunch of dishes. My family use them for the first time this year and we were absolutely delighted. The platters are sturdy, high-quality, significantly larger than the 10 inch paper plates and hold a large amount of food which is essential when you’re serving a large meal.
