These Rubbermaid containers are absolutely best. I like meal prepping for a week. These keep my food fresh for the whole week! They are air tight in my fridge. I can pop them right in the microwave. It’s fantastic. I have gotten so much use out of them. I will definitely recommend. Rubbermaid is a brand you can trust. Survived my dishwasher and me banging them around in my bag. No dings or anything!
