It is part of the latest extension of the Rubbermaid easy find lid system. 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 are oven safe up to 425-Degree f. Plus, a built-in gasket creates a leak-proof seal. The lid is easy to put on and take off and is microwave, freezer, and dishwasher safe. The lid fits right in with the other easy find lids and is labeled with the class logo on the clear top for easy identification.
