I looked forever for one cup round containers again and finally came across these!! So far I love them. I have yet to freeze or use liquid in them yet. It's summer so I am using it for veggies and fruits right now. It has kept my veggies fresh where other containers have not. I just LOVE the bright colors they're fun. But the OCD in me want the lids to match- lol- but I am looking at it as it's fun to change up the color combination! They are easy to clean, I do hand wash most of my dishes so I have not tried them in the dishwasher yet.
