Our Square CR Glass Jars are designed to solve both, offering a sleek, modern silhouette that stands out from standard round jars while providing a certified safety mechanism.

### Why Our CR Jars are the Strategic Choice for Your Brand
1. Certified Child-Resistant (CR) Security
Safety is non-negotiable. Our “Push-and-Turn” mechanism is designed to be difficult for children to open while remaining senior-friendly for adult consumers. This ensures your brand meets legal requirements for concentrate sales in all regulated markets.
2. The Luxury of Electroplated Lids
Standard plastic caps can make premium extracts look cheap. We offer electroplated lids in gold, silver, rose gold, and gunmetal. This metallic finish provides a “premium heavy” feel that justifies your retail price point and attracts high-end customers.
3. Airtight & Smell-Proof Preservation
Extracts are volatile and sensitive to air. Our jars feature an integrated liner system that creates a total airtight seal. This locks in terpenes and prevents your CBD concentrates from drying out or losing their aroma during storage or shipping.
4. Space-Efficient Square Design
Unlike traditional round jars, the square profile allows for tighter packing in shipping cartons and retail displays. This reduces your logistics footprint and provides more surface area for branding and labeling.
### FAQ: Solving Your Sourcing Challenges
Q: Are these jars suitable for highly viscous concentrates like wax? A: Yes. The wide-mouth design and shallow body heights (ranging from 7.2mm to 9.7mm) allow for easy tool access, ensuring your customers can retrieve every bit of the product without waste.
Q: Can I customize the color of the glass itself? A: Absolutely. While we offer high-clarity flint glass, we also provide opaque white, matte black, and custom UV-blocking color sprays to protect light-sensitive extracts.
Q: What is the benefit of the 57mm diameter series for larger volumes? A: For brands expanding into topicals or larger flower volumes, our 57mm Diameter Series (60ml to 180ml) uses a uniform lid size across all heights, simplifying your inventory management.
Q: How do you handle international wholesale shipping safety? A: we use export-grade corrugated dividers and professional palletization. Our breakage rate for bulk shipments is consistently below 1%.
