This is a reusable vape pen that comes with the battery, charger and full tank. Pure Pull uses only the finest flower in their state of the art CO2 extraction machine. The pens are sexy, discrete and the exhaled vape has nearly no smell. As the oil is a concentrate, a little goes a long way. The occasional user will find a cartridge lasting months or approximately 200 pulls. This is a premium, lab tested, CO2 extracted, terpene enriched cannabis oil with no additives and no carriers.
