Packing leftovers, storing ingredients, and meal prepping all come with the same challenge — finding containers that don’t leak, stain, or take over your fridge. The 12-Piece Smart Seal Glass Container Set solves all three. These glass food storage containers with lid readily withstand temperature changes, moving seamlessly from freezer to a preheated oven or microwave, making it easy to store and reheat soups, vegetables, cooked grains or marinated proteins. Made from non-porous borosilicate glass, they won’t absorb stains or odors, so containers stay clear and your meals fresh. Each container is topped with a Smart Seal™ lid featuring four locking tabs and a removable gasket that creates an airtight, leakproof seal for everything from fruits to sauces. The lids are interchangeable with any same-size OXO Smart Seal Glass Containers, letting you build a flexible storage system that adapts to your routine. When space is limited, the modular, nesting design keeps your cabinets and refrigerators organized. Durable, easy to clean, and designed for everyday use, these lock storage containers simplify how you store food. Set includes: Two 4 oz. Rectangle Containers, Two 1-Cup Round Containers, One 1.6-Cup Rectangle Container, One 3.5-cup Rectangle Glass Container, and Six Plastic Locking Lids.
