Each pack comes with one, 1 gram, 510 threaded (goes on a battery) sativa cartridge of flavored 'Watermelon Splash.' ---- A live resin cartridge is filled with cannabis oil extracted from fresh-frozen flower using a solvent-based process (usually butane). Freezing the plant right after harvest preserves more terpenes, resulting in a flavorful, aromatic, and potent vape experience.
