BOOMIBOO [16Pack] Intended For Mason Jar Lids, Wide Mouth & Regular Mouth, Canning Lids, Plastic - Leak-Proof

I haven't used a large ones but the smaller ones fit my small mouth quart sized mason jars. Some of them seemed like they wouldn't fit but as I continue to turn they fit on just fine and they went on very snug and were leak proof.

Is a really handy and attractive especially for non-canning items. Be sure and put in the rubber seal for wet items.

I love the various colors, and the fact that they seal. HOWEVER, I need to warn anyone looking at purchasing them that you need to have good hand strength to use these. We have come to believe that they self-tighten once put on and left. There have been many times I have had to have help opening them - as it, it takes 2 people. One holding the jar & one loosening the lid.Sadly, we have decided that they are not going to work for us and will be going back to metal lids & rings or finding an alternative that seals without making the jar inaccessible.

Seems decent for what I need them for. Only issue was one rubber seal was missing and there's no way to request a replacement. I don't want to go through the hassle of returning them all just for one rubber seal. 🙃

These lids are great for closing up home canned goods for storage in the fridge once opened. Each lid comes with a gasket to help seal up your jars nice and tight.

The regular sized lids don’t fit the standard regular mouth jars. I have both ball and Kerr (as well as random branded jars , 4oz to 16oz) and these are either close to fitting (doesn’t catch the lip to tighten) or they go on so tight I end up breaking the jar trying to get it off. It’s past my return window, just barely got around to this project and will reorder lids from another vendor.

These fit perfect on some mason jars I already had.

I like that they fit the jars, and the colors
