Each pack comes with one, 1 gram, 510 threaded Hybrid cartridge Silk Cocoon. ------ 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.
