Stashbox Tightvac 0.29L — Pocket-Sized Airtight Herb Storage
The Stashbox Tightvac 0.29L is a compact, vacuum-sealed container that keeps your herb fresh, dry, and discreet. Built by TightVac (model TV2), this 0.29-litre stashbox fits in your palm and creates a partial vacuum seal every time you press the lid down — locking out air, moisture, and odour. Toss it in your bag, your jacket pocket, or your desk drawer. Your herb stays exactly as it should: fresh and ready when you are.

Complete your stash setup — pair the Tightvac with a decent grinder like the SLX Non-Stick Grinder or an Integra Boost humidity pack to keep your herb at the right moisture level inside the container. The Boost packs slot right in alongside your herb and maintain a steady 62% relative humidity, which is the sweet spot for long-term freshness.
Why You Need a Proper Stashbox
Here's what actually happens to herb stored in a sandwich bag or an old tobacco tin: it dries out. Within 48 hours, trichomes start to degrade, terpenes evaporate, and you're left smoking something that tastes like cardboard and hits like wet newspaper. We've had customers bring in herb that looked fine but had been sitting in a zip-lock for a fortnight — bone dry, zero flavour. That's not a storage solution. That's a slow funeral for your stash.
The Tightvac solves this with a dead-simple mechanism. You press the lid down, it pushes air out, and a one-way valve holds the partial vacuum. No latches, no screw threads, no fiddly clasps. Just push and done. The polypropylene body is BPA-free, doesn't leach chemicals, and won't crack if you drop it on concrete — we've tested this more times than we'd like to admit. It's not indestructible, but it'll survive the bottom of a rucksack, a festival, or a clumsy morning.
The honest limitation: at 0.29 litres, this is a carry-around container, not a long-term storage vault. It holds roughly 8 grams of ground herb, give or take depending on density. If you're looking to store an ounce or more, step up to the Tightvac 1.3L or the Kilovac range. But for daily carry — grabbing what you need for the day and heading out — the TV2 is the one we'd pick. It's lighter than a phone, fits in a jacket pocket, and genuinely does not smell. We've walked past sniffer dogs at festivals with one of these. No drama.
How to Use the Tightvac 0.29L
- Remove the lid by pressing the release button on top and pulling upward. You'll hear a slight hiss as the vacuum breaks — that's normal and means the seal was doing its job.
- Fill the container with your herb. Leave about 1 cm of headspace at the top — packing it to the brim stops the vacuum from forming properly.
- Place the lid back on and press down firmly until you hear a click. The patented valve pushes excess air out and locks.
- To check the seal, try lifting the lid without pressing the release button. It shouldn't budge. If it lifts easily, press down again — sometimes it takes a second push to engage fully.
- Store upright when possible. The seal works in any orientation, but keeping it upright stops loose material from getting into the valve mechanism over time.
- Clean periodically with warm water and mild soap. Avoid abrasive scrubbers — they can scratch the interior and create micro-grooves where residue builds up. Air dry completely before refilling.
