You could consider using the 100 cc/ 3.4 oz decorative jars (like this or something similar https://www.amazon.com/Mini-Glass-Mason-Jars-Small-Lids/dp/B07F8WGHRC ) and using paraffin to seal the top of the jam. People say that it's dangerous using wax sealer, but my mother did it all the time with jams, no problem. I wouldn't use it for anything else than jams, however.

Anybody looking to do something similar, I just Marie Kondo'ed the shit out of my stash spot and got these jars on amazon. They're great, they have stickers with reusable chalk pens, they can fit up to a half-o (very tightly) or an eighth without making it look bare. There's also these ones that I originally ordered but when the first one of the jars with the handles came in, I canceled them but they're the same size just a different direction lol. Honestly, if you're like OP or myself and usually get a large variety of Flower, this is the way to go by far and budget conscious. The reusable chalk markers means you don't have to worry if one strain stops getting carried or you end up not smoking anymore of it. Hopefully it helps anyone looking. I used to do the black marker thing till I found these guys.
