Glass jars range from 1 gram micro containers up to 6 oz capacities across clear, frosted, amber, and violet glass formulations. Utilizing non-porous Flint glass forming an impermeable gas barrier prevents volatile terpene loss, preserves delicate trichome structure, and maintains internal humidity during dispensary retail storage.

To cross-reference dram sizing, volumetric fluid drams, and outer heights before staging automated filling equipment, check technical specification tables inside each product listing.

• 1 Gram & 20 Dram Glass Jars: Compact straight-sided glass containers designed for 1g to 2g sample sizes or micro flower portions.
• 30 Dram & 3 oz Glass Jars: Industry-standard 3.5g (1/8 oz) dry flower jars available in clear Flint, frosted, and Grand Puff profiles.
• 40 Dram, 5 oz & 6 oz Glass Jars: Medium-to-large capacity glass jars engineered for 7g (1/4 oz) to 14g (1/2 oz) flower weights.
• Specialty Amber & Violet Glass Jars: 40 dram amber glass and 100ml biophotonic violet glass containers built to block UV light spectra.

Closure bundling varies by item, with select SKUs including caps while other glass jars sell caps separately to allow custom lid pairing. Closures certified under ASTM D3475 and Title 16 CFR 1700.20 utilize push-and-turn continuous-thread lug mechanisms to maintain child safety and airtight sealing.

Straight-sided glass sidewalls feature zero vertical body taper, preventing label bubbling and skewing during automated wrap application. Flush cylindrical sidewalls allow high-speed pressure-sensitive labellers to apply state compliance text and dispensary branding smoothly across production batches.

Straight-sided glass jars support full-wrap pressure-sensitive vinyl labels, top-cap compliance stickers, or custom printed outer display boxes. Applying custom pressure-sensitive labels directly to straight-walled jar bodies delivers space for mandatory nutrition panels, strain branding, and legal compliance text.
