Review on Ultimate Leak-Proof Platinum Silicone Sealing Lid Inserts/Liners for Mason Jars - 10 Pack (Wide Mouth) by Amy Smith

Two piece metal lids are very difficult to put on and take off when storing food in jars. These liners allowed me to reuse the metal portion of the rim, essentially making the duo a one-piece, durable and leak-proof cap. The silicone part does not fall out when opening the jar, but can be removed for washing. A bonus for me is that I make large batches of chicken broth that I freeze in jars. I actually had jars in the freezer when the liquid expanded, but with these lids that's no longer a problem. canning storage. Easier to work with than metal liners, they're dishwasher safe and convert metal rims into convenient one-piece glass lids. I've bought plastic lids to use without canning, but they're not ideal as they tend to leak and don't always clean in the dishwasher. Also, they are bulky to store when not in use. I still use the ones I have with extra pads but I find they meet my needs and have no downsides.
