Glass Jars

Glass Stash Jars | Airtight Freshness & UV Protection

When it comes to long-term storage, glass remains the gold standard. At R420.ie, we stock the largest selection of glass stash jars in Ireland, designed to keep your herbs in peak condition. Whether you want to show off the vibrant colour of your stash or keep it shielded from the sun, our jars provide the perfect airtight environment to lock in potency and flavour.

Why Glass is the Connoisseur’s Choice

Unlike plastic tubs or baggy film, glass is non-porous. This means it won't absorb smells over time, and more importantly, it won't strip the precious trichomes from your herbs through static electricity.

Terpene Preservation: Our jars feature silicone or rubber gaskets that create a 100% airtight seal. This prevents your favourite aromas from leaking out and stops oxygen from drying out your stash.
Chemical Purity: Glass is inert. You’ll never have to worry about BPA or "plastic taste" contaminating your flower.
Humidity Control Compatible: Our jars are the perfect size to pair with Boveda or Integra humidity packs, maintaining that "perfect" 62% moisture level.

Our Specialized Glass Range

As Ireland’s premier smoke shop, we offer glass solutions for every need:

Clear Borosilicate Jars: High-quality, heat-resistant glass that allows for total visibility. Perfect for the shelf where you want to admire your collection.
UV-Protected "Black" Glass: The ultimate in preservation. These jars (often called Miron or Biophotonic glass) appear black but actually filter out harmful visible light while allowing beneficial infrared and UV-A light to pass through. This significantly slows the degradation of your herbs.
V-Syndicate SmartStash: The "all-in-one" glass jar. These feature a built-in grinder plate in the lid and a humidity pack compartment, making them the most functional jars in the country.
Mason Style Glass Jars: Featuring a classic heavy-duty "swing-top" clasp and rubber ring for a satisfyingly loud and airtight seal.

Freshness You Can Trust

From 5ml "pocket" jars to massive 1-litre curing jars, R420.ie has the best value in Ireland. We know glass is fragile, which is why we take extra care with our "armoured" packaging to ensure your jars arrive in perfect condition.
