The bottom and top are thick glass but the middle part is thin. A V shaped chunk out of it broke after popping the top. IMO, look for a for a generic jar with thicker glass.

420 science gave me one for free that I forgot about until the other day when I found It stored away with a large amount of product. Must have been there for at least six months, I opened It and It was still fresh. Inserted a new Boveeda bag and today It's as fresh as day one. These pop top glass containers are the best storage containers I've ever used. Nothing else has lasted six months inside a jar by Itself.
