Quarter-ounce jars use a 40 dram (5 oz) volumetric capacity to hold 7 grams of dry flower. Heavy-wall Flint glass, Amber glass, and impact-resistant PET plastic options provide non-porous barrier protection to prevent terpene evaporation and keep flower fresh.

To cross-reference specs before ordering, check technical specification tables inside each product listing.

• eBottles Glass & PET 40 Dram Jars: Straight-sided, wide-mouth containers built for 7g flower capacity and automatic labeling lines.
• 40 Dram Amber Glass Jars: Tinted glass containers that block harmful light exposure to protect THC content.
• V3 5 oz Round Reserve Jars: Heavy-base glass jars supplied with matching flush caps for top-shelf dispensary presentation.
• Grand Puff 40 Dram Glass Jars: Heavy-wall glass bases built for 53/400 neck finish continuous-thread closures.

V3 Reserve jars include a matching lid, while standalone eBottles and Grand Puff 40 dram jars are sold as bases only and require separate closures. Pairing 40 dram jars with continuous-thread 53/400 push-and-turn caps meets Title 16 CFR 1700.20 and ASTM D3475 standards for retail compliance.

Browse compatible closure options in our 53mm Caps Collection, verify dimensions on our Flower Jar Sizing Chart, or check state packaging rules via our State Compliance Regulations Guide.

Straight-sided 40 dram jars feature zero sidewall taper, preventing label bubbling and creasing on wrap labelers. Smooth cylindrical glass walls allow pressure-sensitive labeling equipment to apply branding and state compliance details cleanly without line jams.
