PERFECT FIT The 110mm diameter screw lids are ideal for making preserves and fit perfectly on identical diameter jars with a thread for 8 snap-in teeth. FOOD SAFE Thanks to the silicone seal inside the lid, the food does not react with the metal, which keeps the lid rustproof and protects the quality of the canned food. AIRTIGHT: The screw lids with 8 locking teeth ensure a secure closure of the jars, both in cold condition and after thermal treatment during sterilization or pasteurization. Easy to use: the practical twist-off closure allows for effortless opening and closing of the glasses, while the contents always remain aroma-tight sealed, whether liquid or dry. VERSATILE The lids come in handy packs of 10 and 50, finished in classic white and reusable multiple times, making them particularly environmentally friendly.
