Stash & storage
by Tightvac
The Stash Jar Vitavac is a vacuum-sealed storage container by TightVac that keeps herbs fresh and odour-free in a pocket-friendly 7cm form factor. With a 0.06-litre capacity (roughly 3.5–5g of dry material), it's built for people who need their stash discreet, portable, and properly sealed — not rattling around in a sandwich bag at the bottom of a rucksack.

Pair the Vitavac with a proper grinder — ground herb packs more efficiently into that 0.06L chamber. The Santa Cruz Shredder and the SLX grinder are both popular companions. If you need more room at home, the larger TightVac containers hold up to 12g and use the same vacuum system. For humidity control inside any container, Boveda 62% packs are worth a look. Worth having both sizes: one for the house, one for your pocket. You can order the Vitavac alongside any of these accessories to get your storage sorted in one go.
A vacuum stash jar actively removes air from the container, slowing oxidation and locking in terpenes — something passive seals like gaskets and zip-locks simply cannot do. Here's the thing we've seen a thousand times behind the counter: someone buys beautiful, fragrant herbs, then stores them in a zip-lock bag or an old film canister. Within a week, the terpenes have evaporated, moisture has crept in, and everything smells like the inside of a coat pocket. Worse, everyone around them can smell it too.
The Vitavac solves both problems at once. The patented press-down lid creates a partial vacuum — you physically push the air out when you close it. That does two things: it slows oxidation (which degrades flavour and potency over time) and it traps aromas inside. We've held a sealed Vitavac up to our noses in the shop with strong-smelling herbs inside and got nothing. Zero. That's the difference between a proper vacuum container and a jar with a rubber gasket that you hope works. According to the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), proper storage conditions — low oxygen, stable humidity — are key factors in preserving the chemical profile of botanical materials over time.
The honest limitation? It's small. Deliberately so — this holds 3.5 to 5 grams depending on how finely ground your material is. It's a travel jar, not a bulk storage solution. If you need to stash an ounce, look at the full-size TightVac range. But for a night out, a weekend away, or just keeping a personal amount in your jacket without broadcasting it to the room, the Vitavac is the best pocket stash jar we've come across. If you want to buy a single accessory that genuinely upgrades how you carry herbs, this is the one. The body is solid — it feels like a chunky marker pen in your hand, not a flimsy plastic tube. You can toss it in a bag without worrying about it cracking open.
Using the Vitavac takes about three seconds: fill, press the lid down until it clicks, and the vacuum seal is active. Here's the full process step by step:
The TightVac Vitavac is the single most repurchased storage accessory in our shop — customers buy one, then come back for a second to keep at home. We've stocked TightVac products since the early days, and the Vitavac is consistently one of the most-grabbed accessories at checkout. It's one of those things you don't think you need until you've used one — then you wonder how you managed without it. The vacuum mechanism is purely mechanical (no batteries, no pumps, no parts to replace), so there's genuinely nothing to break. We've had the same demo unit on the counter for years and it still seals perfectly.
One thing to keep in mind: the Vitavac works best with dry material. If your herbs are still slightly moist or sticky, they'll compress against the walls and be harder to get out. Give them a proper dry first, or use a small piece of parchment paper as a liner if you're in a pinch. Also, don't overfill it — the vacuum only works when the lid has room to travel downward. Stuff it to the brim and you've just got a regular container with no seal advantage. If you're looking to get the most out of this jar, pair it with a Boveda humidity pack to keep relative humidity stable inside the chamber between sessions.
Yes. The vacuum seal traps odours inside the container. We've tested this in the shop with pungent herbs — sealed shut, you get nothing from the outside. The seal holds until you physically pull the lid off.
The 0.06-litre chamber holds roughly 3.5 to 5 grams of dry, ground material. Whole buds or coarser material will sit closer to 3.5g. Finely ground herbs pack tighter, pushing you toward 5g.
Pull the lid straight up to open — you'll hear a pop as the vacuum releases. To close, press the lid down firmly until it clicks. That click means the one-way valve has expelled excess air and the seal is active.
Absolutely. The 0.06L size works well for vitamins, pills, small spice portions, loose tobacco, or cosmetic samples. Anything dry and small enough to fit through the opening is fair game.
A mason jar seals with a rubber gasket but doesn't actively remove air. The Vitavac's press-down mechanism pushes air out, creating a partial vacuum that slows oxidation. It's also 7cm tall versus a standard mason jar's 12–15cm — not really a contest for portability.
Yes. TightVac containers are made from food-safe, BPA-free materials. Safe for storing anything you'd put in a kitchen container.
The seal is mechanical — no rubber gaskets to perish. As long as the lid and body aren't cracked or warped, the vacuum mechanism works indefinitely. We've had shop units last years without any loss of function.
You can order the Stash Jar Vitavac directly from Azarius. It ships from our warehouse in the Netherlands to most European countries.
