Hash rosin is a solventless concentrate. Cannabis is washed in ice water to separate the resin heads, the hash is dried, then pressed using only heat and pressure, so nothing but the plant goes into the jar.Our hash rosin jars are sold out while we source the next batch. When rosin returns, each listing will show the strain, the grade of hash it was pressed from and whether it is cold cure (thick and buttery) or fresh press (glossy and saucy). Live hash rosin gummies from Tokyo Treats are in stock now.
