Each pack comes with one, 1 gram, 510 threaded (goes on a battery) cartridge, crafted with cured resin from the sativa strain, Green Cr@ck. --------------- A cured resin cartridge contains cannabis oil extracted from flower that has been harvested, dried, and cured — just like the buds sold for smoking. The curing process helps develop deep flavor and aroma, and the extract reflects the original strain’s profile. Cured resin carts are known for consistent potency and full-spectrum effects.
