Combining the natural elegance of a perfect snowflake with their ingenious and versatile lid designs, Charles Viancin's new Snowflake Lids combine beauty with utility for functional universal lids you'll love to show off. Made from durable, BPA-free food grade silicone and designed to create an air and watertight seal on all smooth rims, these unique lids are perfect for cooking, baking, and even storage. Their intelligent design helps prevent messy spills in the fridge and splatters in the microwave allowing you to cook, reheat and store foods quickly and easily. They're so versatile, they'll even keep dishes hot or cold longer on your buffet. To clean your Charles Viancin Snowflake Lids, just pop them in the dishwasher. The lids are heat safe to 500° F, so they're safe for use in the oven or microwave, and cold safe to -40° F for use in the refrigerator.
