Stash & storage
by Tightvac
The Tightvac stashbox is a vacuum-sealed storage container that keeps herbs, tea, coffee, and other aromatic goods fresh and completely odour-free. Unlike a standard jar or ziplock bag, the Tightvac uses a patented push-down vacuum lid that forces air out every time you close it — no pumps, no fiddling, just press and done. Available in three sizes (0.57L, 1.3L, and 3.8L), there's a Tightvac for your pocket stash and one for your entire collection.
| Size | SKU | Approximate Herb Capacity | Best For |
|---|---|---|---|
| 0.57L | HS0231 | 15–40g depending on density | Daily carry, travel, desk drawer stash |
| 1.3L | HS0232 | 40–100g depending on density | Weekly supply, kitchen counter tea or coffee storage |
| 3.8L | HS0233 | 100–300g depending on density | Bulk storage, long-term freshness, multiple strains |
The 0.57L is the one that fits into a backpack or large jacket pocket. If you're storing loose-leaf tea or coffee alongside your herbs, the 1.3L hits a sweet spot — big enough to be useful, small enough to tuck into a cupboard. The 3.8L is proper bulk territory; we'd pick that one if you buy in larger quantities and want to avoid opening and resealing constantly.

Complete your storage setup: pair the Tightvac stashbox with a Boveda 62% humidity pack to keep herbs at the ideal moisture level inside the sealed container. If you're after something pocket-sized for a single session's worth, check out the Tightvac MiniVac — it holds around 10–30g and slips into a coat pocket.
Here's the thing about herbs, loose-leaf tea, and ground coffee: the moment air gets to them, they start losing potency, flavour, and aroma. Terpenes evaporate. Moisture creeps in — or worse, moisture escapes and everything dries out to dust. A crumpled plastic baggie does approximately nothing to stop this. A glass jar with a screw lid is better, but it doesn't remove the air sitting on top of your stash, and every time you open it, you're flooding the contents with fresh oxygen.
The Tightvac stashbox solves both problems at once. The push-down vacuum lid physically forces air out of the container each time you seal it. You can hear it — a satisfying little click as the lid locks and the vacuum engages. That partial vacuum means less oxidation, less terpene loss, and dramatically less smell escaping. We've had customers walk into the shop carrying a loaded 0.57L Tightvac in their jacket pocket, and you'd never know. That's the whole point.
One honest limitation: the Tightvac isn't a laboratory-grade hard vacuum. It won't preserve herbs for years the way nitrogen-flushed packaging does. What it does is remove enough air to keep things noticeably fresher for weeks to months compared to a standard container — and it does it every single time you close the lid, with zero effort. For daily or weekly use, that's exactly the level of protection you need. If you're looking at genuinely long-term storage (6+ months), pair it with a humidity pack inside and store it somewhere cool and dark.
We've been stocking Tightvac containers since the early days of the shop, and they've outlasted at least four or five other "airtight" storage brands that came and went. The build quality is genuinely solid — the polycarbonate body can take a drop onto a tile floor without cracking, which is more than you can say for a glass mason jar. The rubber gasket in the lid is the part that does the heavy lifting, and after years of use it does eventually wear. When it does, the lid still closes but the vacuum won't hold as tightly. At that point, you're due for a replacement. For most people using it daily, that's a solid 2–3 years of service.
Compared to something like a CVault (stainless steel, heavier, pricier), the Tightvac is lighter and more practical for carrying around. The CVault looks nicer on a shelf, but the Tightvac goes in a bag without adding noticeable weight. Compared to a simple screw-top UV jar, the Tightvac wins on odour control by a clear margin — the vacuum seal makes the difference. If smell is your main concern, this is the container we'd point you towards.
Yes, when the vacuum seal is properly engaged. The combination of the airtight gasket and the partial vacuum means virtually zero odour escapes. If you can smell anything, check that the lid clicked fully shut and that the gasket is clean and undamaged.
For daily-use storage, expect noticeably better freshness for 4–8 weeks compared to an open bag or loose jar. Adding a humidity pack inside extends this further. It won't match nitrogen-sealed packaging for multi-month storage, but for regular rotation it's more than enough.
Absolutely — that's one of the main uses. The 1.3L holds roughly 250–350g of whole coffee beans. The vacuum seal keeps volatile aromatics locked in, so your coffee stays fresher between uses. Just clean the container if you switch between coffee and herbs, as the gasket can hold residual scent.
Yes. The body is made from BPA-free polycarbonate and the lid from ABS plastic. Both are food-safe materials. The rubber gasket is also food-grade.
No pump needed. The Tightvac lid creates the vacuum mechanically when you press it down. The air is pushed out through a one-way valve as the lid compresses, then the seal locks automatically. It takes about one second.
The 0.57L handles 15–40g comfortably and fits in a bag or large pocket — best for daily carry. The 1.3L suits a weekly supply or mixed storage. Go for the 3.8L only if you're buying in bulk or storing multiple types separately.
Hand-wash the lid with warm soapy water — don't submerge it or put it in the dishwasher, as this can warp the gasket over time. The body is top-rack dishwasher safe. Dry everything completely before resealing to prevent moisture buildup inside.
