yes, I don’t have any, but have read they work good. Someone here uses them for bud. I am cheap, mason jars are 12 for $8 here…
If I remember correctly, they even have a little thing/slot underside of the lid to put your bovida pack in…
@jmlove123 sure, but mason jars are cheaper! Those vaults are usually what people keep their personal stash in!
It will be my personal stash lol 
They do have big ones, description claims it can hold a 1/2 pound…

Now those are nice, first time I’ve seen those. Would love to get one of those as a gift. But probably couldn’t talk myself into spending the cash for it, but do love the lid display. I just use the “squeeze” method of checking my humidity…
I will make it be a gift for my self maybe for Valentine’s Day 
Those are nice. Expensive if you grow a lot of meds though.
I will make my own @Ron330, like this one. Just wait for my humidity meters to arrive after that i will install them on my jars 
I have 2 cv container the small one like you posted @jmlove123 they work great. I love it holds plenty and even helps rehydrate the really dry bud. If you look I think I paid 23$ for one of the small ones. I got one at local smoke shop and one on amazon. Both were 23$.
