Onyx Pressed 80-90% Melt We go all-out to produce this truly exceptional product. Our highest grade of pressed hash, Onyx Label products are made from sun-grown cannabis flowers, hand-picked and flash-frozen to capture the maximum amount of flavorful terpenes. Inspired by the hand-rubbed charas hash of India, we use our signature cold-water method to transform cannabis flowers into an unbelievably flavorful live-pressed cannabis hash.
