Review on 12-Piece Multi-color Joseph Joseph Nest Plastic Food Storage Containers Set with Airtight Lids - Microwave Safe by Bobby Valadez

love them for the colors, sizes and easy storage. My biggest problem is durability. You have to be VERY careful when putting the lids on. If you tilt it even a little bit and push down, you'll permanently warp the plastic in the lid and it will NEVER be tight again. This has happened to a few of mine and they are no longer airtight or sealed. I've tried all sorts of ways to bend the plastic back into shape; nothing happens. As long as you handle them carefully, they are completely airtight. Not suitable for the microwave, but I knew I needed it. They get super clean in the dishwasher. I like the wide range of sizes. Each size has a different color so you can easily tell them apart. Each container has a small colored dot on the bottom to match its lid in case they separate. They nest inside each other, saving a lot of closet space. FYI, there is a paper-thin sheet of plastic at the bottom of each container when you unpack it. It's easy to miss. Remove before washing.
