### Why the 3g/9g CR Series Solves Your Business Needs
1. Certified Child-Resistant (CR) Push-and-Turn Safety
Safety is our priority. Each jar is equipped with a certified CR push-and-turn lid, providing a reliable child-lock mechanism that meets strict global safety regulations for cannabis and pharmaceutical distribution.
2. Straight-Edge vs. Rounded-Corner Flexibility
We provide the freedom to choose your aesthetic. Our straight-edge square jars offer a modern, stackable look that maximizes shelf space, while our rounded-corner jars provide a classic, ergonomic feel that is comfortable for customers to carry.
3. Total Preservation of Terpenes and Potency
Extracts are highly sensitive to environmental exposure. Our jars feature an airtight seal that locks in moisture and prevents the evaporation of volatile terpenes, ensuring your CBD or cannabis concentrates maintain their aroma and effectiveness from the factory to the consumer.
4. Wide-Mouth Accessibility for Easy Filling
The low-profile design and wide mouth diameters (up to 37.4mm) make these jars incredibly easy to fill on automated production lines and even easier for customers to retrieve every milligram of product.
### Frequently Asked Questions (FAQ)
Q: Which size is best for 1 gram of concentrate? A: The 3g Square or Round jars are the industry standard for 1g to 1.5g of dabs or wax, providing a “full” look without crushing the product.
Q: Are these jars suitable for liquid oils or just solids? A: While primarily designed for concentrates like wax and resin, the airtight and smell-proof seal makes them suitable for viscous oils as well. However, for thin oils, we recommend our specialized personal care bottles.
Q: Can I customize the lid finish? A: Yes. As a custom glass packaging manufacturer, we offer matte black, gloss white, and luxury electroplated finishes (gold, silver, rose gold) to align with your brand’s color palette.
Q: What is the benefit of the uniform 57mm series you offer? A: For larger volume products (60ml–180ml), our 57mm Diameter Series allows you to use one lid size across all jar heights, significantly reducing your inventory complexity.
Q: Do you offer bulk pricing for a mix of square and round jars? A: We certainly do. Get bulk pricing that supports your growth. We can arrange mixed wholesale orders to help you test different designs with your target audience.
