Very good quality of plastic

They're durable, they stack, and they're convenient for holding our eggs safely on the counter. Bonus is that they hold 14 eggs too!

I love these egg storage containers.

Love this to keep my fridge organized and nice looking.

I still gave it 5 stars because I used it for smash burgers (meatball size hamburger balls) transport for camping. I had to use blue painters tape to secure lid (you could use rubbberbands too) and they worked great. I bought 2 - use the other one for eggs. Love that they are hard plastic, stackable and easy to clean. Worked great for my purposes/needs.
