Stash & storage
by Royal Queen Seeds
The Re:stash Jar 8oz is an airtight, BPA-free storage jar designed to keep your herb fresh, odour-free, and protected from heat and light. Made by Royal Queen Seeds with a hemp-based lid and silicone sleeve, this 8oz jar is built from renewable materials and sized right for home use or travel. If you've ever opened a bag of bone-dry, flavourless herb after a week of poor storage, you already know why a proper stash jar matters.
A dedicated airtight stash jar stops the two things that ruin stored herb fastest: air exchange and light exposure. Plastic bags let terpenes evaporate within days. Tupperware containers create static that pulls trichomes off your buds and sticks them to the walls. The Re:stash Jar tackles both problems with a glass interior jar wrapped in a protective silicone sleeve, topped with a child-resistant hemp lid that seals tight.
We've had customers bring in herb stored in sandwich bags for a fortnight — smells like cardboard, crumbles to dust. Then there's the lot who use mason jars but leave them on a sunny windowsill. Light degrades cannabinoids and terpenes faster than most people realise. The black silicone sleeve on this Re:stash Jar blocks light and insulates the contents against temperature swings. It's a small detail that makes a genuine difference over weeks of storage.
The honest limitation? At 8oz (roughly 230ml), this jar won't hold a massive harvest. If you're storing 50g or more, you'll want multiple jars or something bigger. But for everyday use — keeping a week or two's worth fresh and smell-proof — the 8oz is the sweet spot between portability and capacity. It fits in a jacket pocket or rucksack without drawing attention.

The first thing you notice is the weight — it's heavier than a plastic container, which immediately tells you the glass inside is proper thick. The silicone sleeve has a soft, slightly grippy texture that makes it comfortable to hold and unlikely to slip off a table. Twist the lid and you feel the resistance of the child-resistant mechanism — it takes a deliberate push-and-turn, not just a casual twist. That's reassuring if you've got curious kids or housemates around.
The RQS logo is printed cleanly on the sleeve. Nothing flashy, nothing that screams "stash jar" to anyone who doesn't already know. It looks like a reusable coffee cup from a distance. Pop the lid off and you get that satisfying seal-break sound — proof the airtight closure is doing its job. No herb smell escapes when it's sealed. We tested this with our noses about 2cm from the lid. Nothing.

The mason jar is a decent budget option, but it does nothing about light — and light is what breaks down THC into CBN over time. According to research on plastic pollution and material degradation, plastic containers can also leach chemicals over time, especially with temperature changes (Zhao et al., PMC, 2021). The Re:stash Jar sidesteps that entirely with glass and silicone. If you're storing anything you care about keeping potent and flavourful, the Re:stash is the best stash jar for daily use in this price range.
Complete your setup with an RQS grinder for a consistent grind before jarring, or grab a Boveda humidity pack to maintain the ideal 58-62% relative humidity inside your stash jar. A grinder and humidity control pack alongside the Re:stash Jar is the full freshness kit.
After 25 years of selling storage gear from our Amsterdam shop, the number one freshness killer we see is still the same: people storing herb in whatever container is closest. Coffee tins, old supplement jars, plastic sandwich bags. Every single one of these lets air circulate, and most let light in too. Within 5-7 days, terpenes start evaporating. Within 2-3 weeks, you're smoking something that tastes flat and feels weaker.
The second most common mistake is storing in the fridge or freezer. Cold temperatures make trichomes brittle — they snap off at the slightest touch. The Re:stash Jar tolerates temperatures from -18°C all the way up to 204°C, so it can technically handle a freezer, but we'd still recommend a cool cupboard instead. Room temperature, dark, airtight. That's the formula. This jar delivers all three without any fuss.
The 8oz Re:stash Jar holds roughly 230ml of volume. In practice, that's about 10-14g of loosely packed dried flower, depending on bud density. Leave a bit of headspace at the top so the lid seals properly against the glass rim.
Yes. The airtight seal on the Re:stash Jar stops odours from escaping. We held it right up to our noses with pungent herb inside — nothing. As long as the lid is properly engaged (push down and twist), no aromas escape during storage or travel.
The Re:stash Jar uses a patented push-and-twist mechanism. You need to press the lid down while turning anticlockwise to open it. A simple twist alone won't release it, which keeps curious children from accessing the contents.
The glass interior is dishwasher-safe, but we'd recommend hand-washing the silicone sleeve and hemp lid to preserve their longevity. Warm water and a mild soap are all you need. Let everything dry fully before reassembling.
Look for white or grey fuzzy patches on the surface of buds, a musty or ammonia-like smell when you open the jar, or a damp, spongy texture. Keeping your Re:stash Jar in a cool, dark place and maintaining humidity between 58-62% (a Boveda pack helps) prevents mould from forming in the first place.
Metal containers block light well but can impart a subtle metallic taste over long storage periods. The Re:stash Jar uses glass inside, which is flavour-neutral, and the silicone sleeve provides equivalent light blocking. For an 8oz everyday jar, we'd pick the Re:stash over metal for taste preservation alone.
The lid is manufactured from hemp-based material rather than petroleum-derived plastic. Hemp is a rapidly renewable crop that requires minimal pesticides and water to cultivate. Combined with the BPA-free glass jar and reusable silicone sleeve, the Re:stash Jar is one of the more environmentally responsible stash storage options available.
