Good size and sturdy
Size: 1 X Pack of 180
I was worried about ordering these online but took the chance and they are perfect. Perfect size and sturdy. Meaning they are very close to the size of my regular silverware and they don't break when trying to cut something with the side of the fork etc.

Eco-Friendly and Sturdy - Perfect for Any Occasion!
Size: 11*8in-100pack, Color: White
These plates are fantastic! The 5-compartment design is super convenient for keeping food separated, especially during parties or gatherings. They are incredibly sturdy and hold up well even with heavier meals—no bending or leaking at all! What makes them even better is that they are compostable and eco-friendly, so I feel good about using them without adding to environmental waste. The size is perfect, and they come in a generous pack of 100, making them great value for the price. Highly recommend these for anyone looking for durable and environmentally friendly disposable plates!

Perfect for RV Trips & Grandkids
Size: 11*8in-100pack, Color: Brown
Perfect for RV Trips & Grandkids We purchased these JOLLY CHEF compartment plates for RV trips with our grandkids, and they’ve been terrific. The divided sections are perfect for keeping foods separated, especially for picky little eaters who don’t want everything touching. 😉 They’re surprisingly sturdy for disposable plates and hold up well with heavier foods without getting soggy or flimsy. I also appreciate that they’re made from plant fiber instead of foam or plastic-lined paper plates. Cleanup is quick and easy, which is always a win in RV life…saving water. Couldn’t ask for more! I will absolutely repurchase when in need to refill. I hope that this review helps you decide. I know it’s what I would’ve liked to hear when picking out compartment paper plates.
