Stash Jar Vitavac — Pocket-Sized Vacuum Storage
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.
Why You Actually Need a Vacuum Stash Jar
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. 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.
How to Use the TightVac Vitavac
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:
- Remove the cap by pulling it straight up — you'll feel the vacuum release with a satisfying pop.
- Fill the container with your dry herbs, spices, vitamins, or whatever you're storing. Leave about 5mm of headroom at the top so the lid can compress properly.
- Place the cap back on and press down firmly until you hear or feel the click. This pushes excess air out through the one-way valve and creates the vacuum seal.
- To check the seal, try lifting the container by the lid alone — if it holds, you're sealed. If it pops off, press down again with a bit more force.
- Store upright in a pocket, bag, or drawer. The vacuum holds indefinitely until you open it again.
- Clean between uses by rinsing with warm water and mild soap. Let it air-dry completely before resealing — moisture trapped inside defeats the purpose.
