Now, you can enjoy the organization benefits of the Easy Find Lids system with the versatility of glass. Like other Easy Find Lids products, Rubbermaid Glass containers have lids and bases that neatly nest for compact storage. Lids snap to bases and other lids to make finding the right lid a breeze. Glass bases are designed to stack neatly, which saves space and prevents them from getting stuck together. Rubbermaid glass containers are also ideal for reheating foods in the microwave and the glass bases are oven safe up to 425°F. Plus, a built-in gasket creates a leak-proof seal.
