High Quality Product Using Platinum Cured Silicone.
These appeared to be what I’ve been looking for as they are reported to employ platinum cured silicone. This info was only made available by searching with the AI, so I’d really recommend the seller put it up front in the listing. It’s a huge selling point that they are using platinum cured silicone and really differentiates this product from others.Here’s what the AI said: The EcoPeaceful Mason Jar Lids you're looking at use 100% pure silicone gaskets - but they're made using platinum cure technology!This means:A superior curing process that creates ultra-pure, medical-grade siliconeNo toxic peroxide catalysts (unlike cheaper alternatives)Results in odorless, tasteless, and completely food-safe sealsHigher durability and temperature resistance than standard siliconeThe platinum cure silicone gaskets in these lids are specifically highlighted as a premium feature - they mention paying extra for the best silicone quality and food safety.My finding is that the lids are good quality and make an excellent seal for most things, but particularly smelly VOCs will still permeate and penetrate this silicone.

Love these lids! From the eco-friendly packaging to the quality!
Maybe silly but I shopped for a few weeks for wide mouth jar lids. I wanted lids that did not rust and I preferred no plastic. These are awesome - get them. I wanted stainless steel lids that did not have to have a silicone gasket (just an extra thing to clean). The lids do come with high quality silicone seals (great for storing liquid to allow for no leaks) but I can remove them for dry goods and the lids still screw on nice and tight. So they’re versatile. They have the classic look of canning lids but are more simple to use and store. Packaging was great too - no plastic. I really am so happy with them! Definitely worth it!

Works great
Wonderful product. We do not can anything we just use the jars for storage. The lid fits very well. Easy to put on and remove. I do like not having to remove the ring then pop open the lid. They are a little bit expensive but I’m guessing that they will last longer than the original lids and being stainless steel I do not have to worry about rust

Durable, Non-Toxic, and Perfect for Everyday Use
The EcoPeaceful 316 stainless steel mason jars are high-quality and built to last. The surgical-grade steel feels solid and safe, no worries about chemicals, rust, or glass breaking. I’ve used them for everything from food storage to smoothies and even meal prepping, and they clean up easily without holding odors or stains. The lids seal tightly, and the sleek design looks great in the kitchen or on the go. If you're looking for a non-toxic, reusable alternative to plastic or glass jars, these are a smart and sustainable choice.

High quality is well worth it
Very high quality stainless steel, rust proof. Did not know that some silicone products are inferior. These lid liners have no fillers in the silicone. Well worth the higher price than other cheaper replacement lids. P.S. not for canning.

Amazing non-toxic lids. Sturdy, made to last, and ZERO rust
Exactly what I was looking for. Our family stores all of our leftovers in mason jars (easier to see tall jars in the fridge so food doesn’t sit and spoil in low containers where it can be missed). We use so many dishes, it’s very hard to keep up hand washing and drying all of our original tops. The standard mason jar lids have all accumulated rust, which I then do not want near or touching our food. These lids are VERY well made, the lid fits just right with the jars I currently own, and I get to stick them in the dishwasher without a worry which is a huge win for our house. No more rust and ease of mind knowing we’re using a non-toxic alternative that’s better than the original. Awesome product!

Non-Rusting Lids
Love the lids, but NOT for use with hot contents. These are great for dry storage. The issue is that if you put hot contents into your jar and close, the vacuum will suck the silicone sealer disk into the contents. The beauty of these lids is that they don't rust.
