Can I use Intelligent LIDS on my antique and collectible mason jars?

We hope so! But we can’t guarantee it. The openings may vary ever so slightly different from modern jars and that may affect the non-leaking seal. Definitely try them out at home, tip them, lay them on their side for awhile then set them upright for a while. Then…. if they’re watertight…. use them with your Intelligent LIDS!
