Strong, convenient, and perfect for busy setups
Style: 20 Ounces, Size: 150 Count (6 Packs of 25 Bowls), Style: 20 Ounces, Size: 150 Count (6 Packs of 25 Bowls)
These bowls are a staple in both my home and now adding them to Airbnb property. They’re sturdy enough to handle soups, cereals and even heavier meals without getting soggy or collapsing too fast. I love that they’re microwave safe and compostable makes cleanup easy and eco-friendlier. The 20 oz size is generous and the pack of 6 lasts a good while for sure especially when you’re hosting guests or just want a no-fuss option for meals (or for the teenage boys and their friends coming for a quick bite). You'll appreciate the convenience, and I appreciate not having to worry about dishes piling up all the time. Design and color has some fun to it over the typical white basic kind. Definitely a good value and also doesn't have that weird scent or doesn't leave that weird taste to it.
If you’re looking for durable, disposable bowls that don’t feel flimsy, these are a solid pick.

Sturdy heavy duty plates
Style: 20 Ounces, Size: 150 Count (6 Packs of 25 Bowls)
I have bought these Dixie plates for a few years. They are very good, sturdy plates. I also have the bowls to match. Plates are sturdy and will not bend like regular paper plates
