CR Mason Jars

The CR Mason Jar has been a forever staple in storing flower. The Bureau has crafted custom CR Mason Jar sizes in two styles to perfectly fit the most popular quantities of flower. These jars are completely airtight, thanks to our patent-pending silicone ring technology, and feature graduated measurements of mL on one side and cups/ounces on the other, encouraging the end-customer to keep this jar for use as a piece of glassware in their home.
