Review on 🥗 CARTINTS Green Collapsible Food Storage Containers: 4 Piece Set with Lids, Silicone Lunch Containers, Microwave and Freezer Safe by Steven Stager

I recently got the Cartinits 7x3" round containers and love them. They are all one size and large. They are air very tight. Once you close the buckles on the lid and press down, there is an airtight seal and the air pressure prevents the container from collapsing. But with their rectangular ones, each is a different size. I prefer at least 2 large and 1 medium as the little one is less useful. These are NOT AIR TIGHT. Air leaks and then the containers collapse when you press on them. Water leaks where the air leaks. Therefore I'm a bit disappointed with the rectangular set versus the spectacular round set.
