Muv has several options for cartridges. I found the Pure cartridge fit my existing pen, so this is the one I decided to go with. I was happy to see it is solvent-free, and only contains distillate with cannabis-derived and all natural terpenes, providing full spectrum benefits. Blueberry is one of my favorite strains, so I was excited to try it in a concentrate. As I suspected, the concentrate isn't quite as effective for me as the whole flower, but it is still a decent alternative if you have to be discrete, or whole flower isn't your thing.
