That’s a great sale price! I bought a bunch also, but now I’m hoping I didn’t buy too much. I’m hoping they will last as long as I need them to.
That was several years ago. I haven’t used many, because I have to keep buying new jars. Every year I run out of old ones to use. Pantry is growing. LOL
They will last, provided they are protected from moisture and sunshine.
Many people store excess rings and lids in a plastic bag to keep them clean and rust free; most people store in a basement, but humidity there is a damage factor.
If you add silica gel packets, you are able to store for a longer period without damage, and the silica gel can be reconditioned.
The best sources for surplus silica gel are shoe stores, electronics equipment, and piano stores where humidity needs to be controlled during transport.
The silica gel packets are generally marked as :" Silica Gel, do not eat."
The silica gel packets can be reconditioned and moisture removed by placing in a microwave oven, and microwave for a minute or two, depending on the number and size of packets.
