Review: Long Lasting, Use Over and Over - I use these in my metal lids on pint and quart canning jars for mushroom liquid culture. They last quite some time and I have used them over and over with success. They would probably last even longer, but I just choose to use new ones. And yes, they can go in the pressure cooker on your jars. A good quantity for a good price.
Review: Great value - These have been performing well, I have, however, doubted if they have been truly healing after puncturing because of their price They stay in place and are tough
