Although I love these, I can't find much info about them anywhere.

Mini J's were designed by High Country Healing (HCH) in Colorado. They grow over 50 strains in a garden located in the mountains, above 10,500 feet in Colorado. Unlike most pre-rolls that are made with shake, HCH uses the same flowers that they grow and sell in their store fronts located in Alma, Eagle-Vail, Silverthorne, and Colorado Springs. Each Mini J contains 1/4-gram of cannabis, in contrast to the typical 1-gram joint.
