Some of my Encheng 150 ml clip top jars that I use for smaller quantities. Silicone seals, I think, but they serve the purpose that I intend them to serve.

There are larger clip top jars of other brands with thicker, rubber, gaskets that I used many years ago with very good results, equal to Ball jars, based on over a decades worth of actual experience. But two part lid Ball jars are less expensive and they work fine.
I am firmly convinced that Mylar 7 mil bag, such as the ones from Pleasant Grove Farms, are as suitable as anything else for longer term storage. From a space standpoint, for me they work much better and I have switched from jars to Mylar for about 80% of my long term cellaring.

All of these products are in short supply, a situation that will get worse as people harvest their Covid gardens.
My principal aim in tobacco storage is to preserve it in smokeable condition. You can do that with a clean glass peanut butter jar and a Boveda. Age changes how tobacco tastes. You might like the changed taste, you might not. It might taste different pulled from a Ball jar than from a Mylar bag. You might like one over the other. You might notice a difference between tobacco stored in a Ball jar packed tighter than a tick as opposed to one with air space left. Or not. You might like one versus the.other. Or not. Or, at least as likely, your tastes might have changed.
There are lots of ways too keep Tobacco in smokeable condition for short, intermediate or long term use. No one way is right for everyone, “ forum wisdom” or not.
