Cold cured rosin available in Black Label and Purple Label are both presented as stunning pearls of creamy hash. The Black Label is a connoisseur grade rosin produced by refining the highest quality solventless hash while the Purple Label is produced using a wider selection of high-quality hash. These products are carefully extracted using heat and pressure, recovering the desirable oil and terpenes. It is then slowly cured under controlled conditions in glass jars, eventually resulting in the high quality cold cured product that is Soiku Bano's flagship.
