Each pack comes with one, 1 gram, 510 threaded cartridge (goes on a battery) crafted with live resin from the hybrid strain, 'Chem 91 x Dosidos'. ------- 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. These carts are a popular option for users who want true-to-strain flavor and full-spectrum effects — all in a convenient, portable format.
