ZILLIONAIRE HASH ROSIN, the ultimate way to experience the full potential of cannabis concentrates. Each gram of our HASH ROSIN is extracted from age-cured solventless bubble hash, leaving a terpy punch. Rosin, sometimes referred to as solventless hash oil (SHO), is a cannabis extract made without solvents. When a rosin press is used for the extraction, the resinous sap is mechanically separated from the plant and collected onto parchment paper.
