CVAULTby Boveda | 2 oz Storage Container | Air Tight & Light Resistant | Food Grade Stainless Steel | Includes 62% RH 8-gram Boveda Pack

It's airtight metal, at least according to spec. It seems to be at any rate as the smell is greatly reduced when it's sealed.I got a large because I had 70 grams. The "instruction" card that came with this lists 4 sizes, two of which use the 67 gram Boveda and two of which use the 320 gram Boveda.I am someone who had been using Boveda before this and tossing them into my bags. They helped quite a lot (usually I'd get an ounce and toss it in). Larger amounts recently became available here and I got 70 grams. It said the large of this would only hold 2 ounces, so 56 grams, but the thing I got holds the 70 EASILY. I know the Boveda is "only" meant for 67 grams but it's holding an extra 8% worth so I think it'll be fine.I mean in terms of space: the 70 grams I had fit easily into the LARGE version of this. I didn't want to get a small version because, at least for me, an ounce I can feel fine keeping in the bag for the duration that I have it with a Boevda in the bag, but for 70 grams (2.5 ounces) I needed something a bit better because I'll be taking out of it regularly but don't want this gigantic 70 gram bag that is just unwieldly.So, 70 grams fits in there fine. It seems like it could fit even more than that fairly comfortably, but I'm not sure how much you could push it.I saw the larger ones that actually say they're for like 4 ounces and up, and they were 2x the price as this, so I think unless you have amounts over 2.5 ounces you should stick with this. I would also NOT RECOMMEND the smaller once since its only $4 less and you lose a lot of space. You could get away with putting a 1 ounce Boveda into this if you only had once ounce of bud in there I would bet with no issues. I guess if the SIZE is the issue you might want the smaller one, but the value here seems to be in the LARGE VERSION ON THIS PAGE which costs 4 more than the "small" but like 30 less than the next sizes up.Just got it, had it for a day. But it really is airtight as far as I can tell and it is of HIGH QULAITY, at least in my opinion. Some of the welds might not be like a welders dream but they're also pretty small holding small things down so, not sure how great they could be.That's about it. I'd give it 4.5 if I could just because it seems to pickup fingerprints like crazy but in terms of functionality and easily holding what it's supposed to and more it is a 5.

Container is nice and air tight. Spot for a Boveda pack size 8 which is good for 1 oz. The container size is a little small and for regular sized bud you will fit about 3/4 oz. If you decide to cut them down a little or fill the space with smaller popcorn buds you can easily pack in an ounce. What is nice is that Boveda packs don’t just emit humidity, but also absorb humidity to keep your buds perfect at 62% rh!

Significant Dent in the product. Was offered instant refund.2nd time item came undamaged and works perfect.

I have to trust the humidity level suggested by the manufacturer, after three batches in the CVualt I have no complaints. In years past I've used several DIY methods, nothing as easy or accurate as CVault. I have been using the small and med for over a month now and gave 3 small CVaults away as gifts.CVault is simple and well made. A note from my conversations with CS is the CVault works best when full, so take this into account as you pick your size(s).Recommendations from them are-Small- quarterMed- halfPros-Well made and not over engineered.Three clamps are easy to use and seem to provide even pressure on lid seal.Protects from light degradationCons-Only complaint is humidity pack is a little big for the smallest Vault. They all are folded (Follow Directions on this!) but in the small Vault the corners can still overlap the seal. Though, I would rather deal with that then different sized packets at different prices. Personally I don't see the overlap affecting anything that much, but felt it should be noted.Clearly I recommend and I am giving away as gifts. Do some looking when you go to refill the humidity packs, prices vary wildly, good pricing is findable.

They come in different sizes for your convenience

Stellar quality for a reason, perfect seal, weight and size are great design choice

The media could not be loaded. I did read reviews on it being "smaller" but was a little difficult to determine actual size comparisons from the seller. with reviews, I just couldn't get a grasp on the true size. I am able to actually fit just over 29 grams in here of smaller buds. Works like magic and I love the premise, just very small overall and in the future I would definitely have to upgrade about 4X the size with my most recent harvest I have so much exrta I couldn't fit... Love the build quality and it truly does keep it at a perfect humidity, plus is just a solid durable tight seal vault I like it a lot! Just the size bums me out isn't what I was expecting. I hope my pictures and video are helpful on determining size as I was in the same boat!

Great product
