In my own preserving, I've used Kerr jars, the kind that are available at supermarkets and hardware stores. Unlike most products, preserving jars, at least in the United States, appear to have no 'bargain' version and 'luxury' version; there's just the standard utilitarian Kerr/Ball jar, unchanged for decades.
But on a recent trip to Sur La Table, I spotted a curious little cardboard flat of jars that I didn't recognize. I bent over to inspect them, and found that yes, someone had come up with a cleverly designed and fashionable alternative. No metal rings, no razor-sharp metal discs, just a glass jar, a glass lid, and a rubber gasket. I looked up this company, called Weck, and kept their name in my mind, intending to call upon them when my current stash of glass runs out, or when I decide my preserves have become gift-worthy.
