Bulk Pack of 100 Large Mouth Canning Lids You're getting a lot of lids, and the best part is that this pack won't break the bank. Every value pack contains 100 Wide Mouth Canning Lids, each measuring 86mm (3.4 inches) wide with enhanced thickness so that they won't bend or warp. Made from Rust-Resistant, Food-Grade Metal Each thick tinplate is resistant to rust and extreme temperatures - even under high heat, they will not warp or become deformed. Also, they're food-grade, so you won't have to worry about them potentially transferring harmful substances to your food. Equipped with a Leak-Proof Silicone Seal On the bottom of the canning lid, you'll find a heavy-duty silicone seal that does not contain BPA. This high-performance seal creates an impenetrable barrier so that outside elements, including air, cannot sneak inside the jar and ruin your food. Easy to Use - Fill up a Jar & Pop on the Lid Before using a lid, hand wash with soap and water, and let it air dry. Then, fill a jar with food and wipe away any residue. Next, place the lid and rim on, and tighten. Let the jar sit for at least 24 hours, and then push on the lid to ensure it doesn't flex. Creates a Barrier to Keep Foods Fresher, Longer These super-sealing canning lids will keep foreign matter out while locking in all of the flavor and goodness. They're great for preserving jams, jellies, sauces, pickled foods, applesauce, beans, soups, stews, condiments, and more. Reusable & Suitable for Most Popular Jar Brands Our wide-mouth sealing lids are not single-use; each one can be washed and reused many times over, which will save you time. Also, they're designed to fit many popular mason jar brands securely. Space So You Can Jot Down the Date & Contents There are lines so that you can use a marker to write down the date and contents inside of the jar. Labeling each mason jar is essential because, down the line, you don't want to guess what's stored inside and for how long.
