Mainstays Rainbow Polypropylene Food Storage Set, Multi Color, 14 Pieces

We bought the Mainstays rainbow 14-count set because the fridge had become a mystery novel of unmarked takeout boxes. Color lids make it obvious which container is soup versus kid snacks, and the set covers enough sizes that leftovers actually get saved instead of abandoned. They nest reasonably well, lids snap without a wrestling match, and reheating leftovers is less drama when you can grab the right size on the first try. They're plastic, not heirloom glass—don't put them through a dishwasher vendetta or use them as cutting boards—but for weekday food logistics they punched above the price. Keep a Sharpie nearby if your household argues about whose chili is whose.
