Each package comes with one, 1/2 gram, 510 threaded cartridge (goes on a battery), crafted with live rosin from the hybrid strain, Rainbow Belts 3.0. Strain Lineage: Rainbow Belts 2.0 x Moonbow 112 F2 #60 ---- A live rosin cartridge is a premium, solventless cannabis concentrate crafted from fresh, flash-frozen flower. Unlike other extracts, it is created by washing the plant material in ice water to isolate the trichomes, which are then pressed using only heat and pressure—no chemicals or solvents involved. This mechanical process preserves the full spectrum of cannabinoids and delicate terpenes, resulting in an exceptionally clean, flavorful oil that delivers a true-to-plant experience in a convenient vape format.
