Charles Viancin Cherry Blossom Lid is a beautiful and practical alternative to plastic wrap. Unlike plastic wrap, these lids can be used over and over. The lid seals tight on all smooth rims, which means any bowl can be used for food storage. The Cherry Blossom Lid creates an airtight, watertight seal for reheating and storing. It can also be used while serving food, to keep your dishes hot or cold for longer, or simply protecting them at picnics. Each lid is oven, microwave, dishwasher and heat safe up to 428 degrees Fahrenheit.
