Protective: These reusable lids provide a precise sealing solution for glass jars, especially following heat treatment during sterilisation or pasteurisation processes. They shield preserves from oxygen, moisture and insects, extending their shelf life. Convenient: Our lids are available in many different patterns, which enable effortless identification and distinction between varying kinds of preserves. Safe: These lids are made from tinned sheet metal and coated with silicone on the inside. This prevents any conceivable corrosion of the lid by ensuring that its contents do not interact with the metal. User-friendly: The twist-off closure, which measures 82 mm and includes six threads, facilitates effortless opening and closing of the jam jars. Various sizes: For your convenience, our lids are available in a wide range of diameters including 33 mm, 38 mm, 43 mm, 53 mm, 63 mm, 66 mm, 82 mm, 89 mm and 100 mm. They are also sold in four packaging options: 10, 50, 100 and 200 pieces.
