Blue Sky Liquid Diamond Live Resin cartridges are the result of years of work and product development that has brought us to a result we couldn't be happier with. Using proprietary techniques and the utmost care to preserve every terpene, they stand apart from your typical live resin cart in both flavor and effect. These cartridges are 100% single source, whole plant fresh frozen, meaning there are no cuts, additives or distillate. True to the plant in every way. At Blue Sky all of our cartridges are ceramic, and have passed tests for heavy metals!
