With 20 airtight food storage containers in multiple shapes and sizes, this set includes rectangles ranging from 8.1 to 50.7 oz, rounds from 6.1 to 40.6 oz, and small sauce cups of 1-2 oz, offering flexible solutions for storing everything from leftovers to condiments. Made from BPA-free, food-grade materials, these containers are safe for microwave use without lids, dishwasher cleaning, and freezer storage. An improved sealing system with silicone rings ensures an airtight, leak-proof barrier that locks in freshness and prevents odor transfer. The design features four rounded locking latches for easy handling, non-slip bases to prevent shifting, and stackable and nestable forms that save space in cabinets or fridges. Lightweight compared to glass alternatives, they are convenient for daily home use, meal prepping, or transporting food outdoors. Their clear bodies allow quick visual identification of contents, making them ideal for pantry organization. Suitable for fruits, vegetables, salads, meats, snacks, and soups, these durable containers support versatile kitchen needs while maintaining long-term performance through repeated use under varying temperatures.
