First off, I’m obsessed with containers. I have had this particular type in my own home for a long time now. They’re affordable, lightweight and non staining. I’ve had mine for over a year, stored all different types of left overs in them, and washed them at least 100xs in the dishwasher with no melting or warping. The clips are very durable and I’ve had no issues with breakage, and they’re leak proof. I can’t say enough good things about Rubbermaid!
