3oz Glass Jar with Black Child-Resistant Lid

The 3oz Glass Jar with Black Child-Resistant Lid is a clear glass flower jar built for cannabis brands, dispensaries, and processors who need packaging that actually looks good on the shelf and passes compliance checks. It’s sized right for retail-ready 1/8 oz (3.5g) to 1/4 oz (7g) fills, depending on density and trim, with a low-profile form that still gives your flower room to breathe. Heavy-feel glass plus a black child-resistant cap means you get premium presentation without babying your inventory.

Why It Works

• Retail-ready fills — 3oz volume comfortably fits standard 1/8 oz to 1/4 oz flower fills, so your pre-pack menu lines up clean across SKUs.
• Compliance without killing the vibe — Black child-resistant lid checks the regulatory box while keeping your branding front and center on the glass.
• Clean shelf presence — Compact footprint at 2.24 inches (57mm) wide and 2.48 inches (63mm) tall lines up perfectly in rows without eating all your display real estate.
• Built for real production runs — Bulk case options (50, 150, 600, 1500, 4500) scale from small-batch drops to full statewide launches.
• Sturdy in the hand — Thick, clear glass feels premium, so your customers notice the quality before they even crack the seal.
• Easy to label — Smooth walls give you a flat, predictable surface for brand wraps, strain labels, or compliance stickers.

Best For

This 3oz glass jar is made for dispensaries, cannabis brands, and white-label packagers who are pre-packing flower all day and need packaging that won’t slow down the line. If you’re filling a lot of 1/8 and 1/4 jars and want something that looks clean in a display case and stacks well in storage, this is the workhorse you lean on. It also plays nicely with organized back-of-house setups that already rely on dedicated storage and packaging solutions.

How to Use It in Your Workflow

Fill after your flower is trimmed, sorted, and weighed, then apply your brand labels and compliance stickers to the side or lid depending on your design. The child-resistant lid twists on with that familiar push-and-turn motion, giving you a positive lock so jars don’t pop open in transport totes or during delivery runs.

During filling, you can stage open jars in rows on a clean workbench or on a nonstick dab mat to keep kief and crumbs off your table and make cleanup easier when you’re done for the day.

Because the glass is clear, it’s easy to visually QC each jar for fill levels, contaminants, or mislabeling before it ever hits the sales floor. When you’re done with a batch, load them into cases or storage bins alongside other sizes of glass jars and cannabis packaging to keep your SKUs separated and easy to grab for orders.

Specifications

Fit & Use Cases

These 3oz jars shine as a standard flower format: they’re dialed in for 1/8 and 1/4 jars in both medical and adult-use markets. They’re especially handy if you want a single jar size you can run across multiple weights by adjusting label copy and fill volume, instead of juggling a bunch of different vessels. For multi-strain drops, keep your bulk inventory staged in larger containers, then portion into these jars and finish with branded lids and strain labels pulled from your main mylar bag or sticker stock station.

Cleaning & Reuse

For in-house reuse or R&D, just remove labels, then rinse the glass with warm soapy water and let it air dry fully. For stickier residue, let it cool if it’s been near heat, then wipe or soak in isopropyl alcohol, rinse thoroughly with water, and dry before putting anything fresh inside. If you’re reusing for non-retail purposes, you can use them as sample jars, internal QC containers, or to hold test grind for new smoke shop products and accessories.

FAQ

• How much flower does this 3oz jar actually hold?

  In most cases, this jar is ideal for 1/8 oz (3.5g) to 1/4 oz (7g) of flower. How full it looks depends on how fluffy or dense your buds are and how you trim, but those are the standard retail fills people run with this size.

• Are the lids really child-resistant?

  Yes. Each jar comes with a black child-resistant lid that uses a push-and-turn style mechanism common in compliant cannabis packaging. Always confirm with your local regulations, but this format is widely used by legal-market brands alongside other compliant joint tubes and packaging.

• Can I store concentrates in these jars?

  They’re primarily designed for flower presentation and sizing, but some people use them for bulk storage of packaged goods or larger non-sticky items. For sticky extracts and smaller portions, you’ll get better performance and less waste with dedicated concentrate jars or nonstick packaging made for oils and rosin.

• Do these jars come with lids, or do I have to order those separately?

  Lids are included. Each jar ships with a matching black child-resistant cap sized specifically for this glass, so you don’t have to hunt for compatible closures or worry about threading issues.

• Will these jars work for both 1/8 and 1/4 ounce SKUs?

  Yes, that’s one of the main reasons people choose this size. A 1/8 will sit lower in the jar with more headroom, while a 1/4 will fill it out more. Many brands use different label designs on the same jar size to separate their 3.5g and 7g products while keeping packaging consistent.

• How should I store filled jars before they hit shelves?

  Once filled and sealed, keep jars in a cool, dry place away from direct light to help preserve terpenes and presentation. A lot of operators stage them in cases or bins alongside parchment-lined parchment paper packs and other supplies so everything needed for packaging lives in one clean area.

• Are these jars good for non-cannabis products too?

  Definitely. While they’re tuned for flower, the 3oz size and CR lid work great for herbs, teas, or other dry goods where you want a premium glass presentation. Just keep in mind that if you’re in a regulated cannabis market, anything meant for sale should be labeled and used according to your local rules.
