Made for use with dry herbs, or waxy oils, Atmos Vaporizer Pen cartridges have a 510 threading which makes them very versatile. They may be designed for use with the Bullet-2-Go Atmos but any vaporizer pen with the appropriate threading will work with these cartridges.
Presented in black, they offer the freedom of choice that many others don't. Fill one with dry herb, then the other with your favorite waxy oil, and after that, all you have to decide is which one to use first. The budget-friendly price for these cartridges make them excellent gifts, or as a treat to yourself since it never hurts to have a few extra around!
