18oz Child-Resistant Glass Jars with Black Caps – 28 Grams (1 Ounce) Capacity, Airtight and Durable, 24-Pack – The Ultimate Storage Solution for Cannabis Flower, Food, and Crafts

The Oil Slick 18oz Child-Resistant Glass Jars with Black Caps are heavy-duty storage jars built for people who actually move weight — up to 28 grams (1 ounce) of cannabis flower per jar. They’re made for growers, home stash keepers, and brands who need airtight, smell-controlling storage that still looks clean on a shelf. Thick glass, a real child-resistant closure, and an 18oz (532ml) capacity make this 24-pack a serious upgrade from random kitchen jars.

Why It Works

• Keep your flower fresh longer — Airtight seal and thick glass help lock in terps and keep air and moisture swings from beating up your buds.
• Real child resistance — Push-and-turn black caps give you the safety you need around kids while still being easy to open once you know the trick.
• Smell stays where it belongs — Screw the lid down and strong aromas stay in the jar, not floating around your closet or backpack.
• Built to be handled — Durable glass walls feel solid in the hand and stand up better to daily opening and closing than cheap thin jars.
• Brand- and label-ready — Smooth, straight sides are perfect for strain labels, batch stickers, or branding without wrinkles and bubbles.
• Large, true ounce capacity — Sized to comfortably hold 28 grams of dried flower without crushing nugs or over-packing.
• Multi-use workhorse — Just as happy storing gummies, spices, or craft supplies as it is holding your top-shelf.

Best For

This 24-pack is dialed in for people who treat storage as part of the process, not an afterthought. Licensed operators and serious home growers will appreciate having matching jars for multiple strains, phenos, or test batches without the chaos of mismatched containers. If you’re already organizing your stash area with dedicated storage and packaging gear instead of grocery store Tupperware, these belong on your shelf.

They’re also a smart pick for dispensaries and brands that want a heavy-bottom look without flimsy lids, and for crafters or food preppers who like being able to actually see what’s inside at a glance. One set handles flower, infused snacks, and even non-canna pantry items without feeling out of place.

How to Use It

Day to day, these jars are about as simple and reliable as it gets. Fill the jar with your dried flower, snacks, or materials, taking advantage of the wide opening so you’re not jamming big nugs through a tiny mouth. When you’re done, line up the cap, push down, and twist until you feel it fully seat — that’s your airtight, child-resistant seal locked in.

For brands and growers, the straight glass walls make it easy to apply labels in a clean line, without fighting ridges or weird tapering. Many operators stage filled jars on a dab pad or mat at the packing table so any shake, kief, or crumbs land on a nonstick surface instead of raw tabletop.

Crafters and home organizers can treat them like upscale pantry jars: line them up, label what’s inside, and stack or shelf them wherever you need things looking neat. The child-resistant tops mean these can live in more open spots without being as tempting or accessible to curious hands.

Specifications

Fit & Real-World Use

Each jar is sized so a full ounce of properly dried flower fits without cramming everything in and destroying structure. That extra headroom matters when you care how your nugs look coming back out. If you’re juggling multiple strains or SKUs, 24 pieces is usually enough to cover a solid menu or a home grow run with backups.

For concentrates or smaller-format products, a lot of people pair these with smaller dedicated concentrate jars so their flower and dab storage are both dialed instead of trying to make one style do everything.

Cleaning & Care

When it’s time to swap strains or repurpose a jar, just empty it out, then rinse the glass with warm water and a bit of mild soap. For sticky or smelly residue, a quick soak in isopropyl alcohol works well — rinse thoroughly with clean water afterward and let it dry completely before loading it back up. Wipe the caps with a damp cloth and let them dry; don’t soak them for long periods so the closure mechanism stays happy.

How These Compare

Compared to random kitchen jars or cheap plastic containers, these are built for cannabis from the start: child-resistant caps, tighter odor control, and a size that’s actually dialed in for a full ounce. They also feel noticeably more solid than many budget glass options; you feel the weight when you pick one up.

If you’re already using heavy-bottom glass from our broader glass jars & extract packaging lineup for concentrates or specialty items, these 18oz jars slot in as the dedicated flower side of your program so everything still matches on the shelf.

FAQ

• How much flower can each jar really hold?

  Each jar is sized to comfortably hold up to 28 grams (1 ounce) of dried cannabis flower. You’ll still have a bit of breathing room so your buds aren’t crushed or pressed against the lid.

• Are the lids actually child-resistant?

  Yes. The black caps use a push-and-turn mechanism that’s designed to be child-resistant while staying straightforward for adults once you know the motion. It’s the same style you’ll see on a lot of compliant cannabis packaging in legal markets.

• Do these control odor well enough for indoor storage?

  When you screw the lid down all the way, the airtight seal does a solid job of containing strong aromas. If you’re extra smell-sensitive, you can still stash the jars inside a larger container or cabinet, but most people find the odor control more than enough for closets or cupboards.

• Can I use these for non-cannabis stuff?

  Definitely. They’re excellent for pantry items, teas, spices, or even craft supplies like beads, buttons, and pigments. If you’re keeping infused edibles in them, many people still like to wrap or bag individual pieces before they go into the jar, just like they would before dropping them into mylar bags.

• Are these good for retail shelves and displays?

  Yes. The clear glass shows off product nicely, and the uniform black caps keep everything looking clean and intentional. Add your brand and compliance labels and you’ve got a professional, repeatable presentation that matches what customers expect in a modern shop.

• What’s the best way to keep the glass looking clean?

  Fingerprints, dust, or label residue can be wiped off with a soft cloth and a bit of glass cleaner. For heavier residue inside the jar, let it cool if it’s been near any heat, then use a quick isopropyl alcohol rinse, followed by water and a full dry before you refill it. For caps, just a damp cloth is usually enough.

• Do they work for long-term storage?

  As long as you’re starting with properly dried and cured flower and keeping the jars in a cool, dark place, the airtight seal and thick glass are great for longer-term stash duty. Some people also use humidity packs inside the jar to further stabilize conditions, the same way they would when storing product alongside other smoke shop products and accessories that they care about keeping in good shape.
