This all-inclusive glass food storage kit comes with 10 pieces of 21oz (630ml) large containers and 2 pieces of 13oz (400ml) medium containers, paired with 5 mini sauce jars for portion control. Multiple flexible sizes perfectly fit daily meal prep, diet portioning, office lunch packing, leftover storage and weekly kitchen arrangement, delivering greater cost performance than ordinary single-size container sets. Unlike plastic lids prone to discoloration, our premium glass lids stay intact, free of lingering food smells and stains even after long-term repeated use. Fitted with stretchy silicone airtight gaskets, these meal prep containers create a fully spill-proof seal to lock in natural food freshness, stop liquid leaks and avoid mixed food aromas. They work great for holding soup, sauces, salad dressings and moist meals. The non-toxic food storage containers are crafted from premium borosilicate glass with zero BPA and non-hazardous raw materials, providing reliable, wholesome storage for all your food and keeping meals fresh and clean for everyday long-term use. The heat-tolerant glass construction handles wide temperature swings safely, compatible with microwaves, freezers and dishwashers (lids excluded). It will not crack or warp when reheating chilled leftovers or undergoing high-temperature washing, streamlining your daily food storage, reheating and cleanup routines with simple, hassle-free operation. Uniform stackable sizing maximizes usable space inside fridges, cupboards and kitchen racks to tidy up cluttered countertops and storage zones. Ideal for fitness meal prepping, weight management portion planning, daily family food storage and outdoor packed lunches, catering perfectly to the healthy, fast-paced modern lifestyle.
