This set of 6 beautiful Sunflower Silicone Lids will make even your leftovers look good! These lids seal a tight lid on all smooth rims: stainless steel, glass, plastic, and melamine. They prevent spills by creating an airtight, watertight seal for reheating and storing, and can go from the freezer to oven to table with ease. Pop them in the dishwasher when you're done, and they are ready for next time. Now that's easy!
