SHEYNIAN 12 Pack Rubber Seals for Glass Jars, Replacement Silicone Gasket Seal Ring, Silicone seals for 2.75 Inch / 70mm Regular Mouth Canning Jar (White)

They work perfectly. I keep everything in canning jars. I have some older white ball plastic lids that don’t seal as good as the black lids. These rings really helps make them an air tight seal. When I ordered another set I did not search my orders to get the same ones and waisted my $ on them. They were thinner and smaller. They did not go all the way to the inside lid edge and falls out into the jar of food before you can seal the lid. I’m having to toss them. I didn’t realize it until it was too late to return them. The one on the right is this seal that works great.

Works great on all sizes of antique canning jars, and holds a seal well. I use the old style jars for my dried herbs and tea since I don't trust this for actually canning sealing and this works perfectly for what I need it creates an airlock and holds freshness

I liked the flexibility, the size, and the color. My only problem them was that they are slightly larger than what I needed. They still work well for now.

Works for most of my antique canning jars.

good quality, fast delivery,

I got these for a set of old stainless steel salt and pepper shakers I have, they fit inside the lid perfectly and keep salt/pepper from getting in the rim of the shakers making it difficult to get the lids off. These fixed that problem.

They work fine and help seal the plastic lids I am using.

The description stated it would fit Mason Recap but it is too large.
