Made from polystyrene foam, they stick inside metal or plastic lids to create a dust and moisture barrier. Perfect for spice jars, cosmetic containers, pill bottles, or homemade crafts. Easy to use: clean the lid, peel off the backing, press the liner in (black text side up), and screw the cap on. Wait 24 hours for the best seal.
