0.3ml & 0.9mm Glass Cartridge
Our .3ml and .9mm glass cartridges are excellent. They are made from borosilicate glass, and contain stainless steel internal parts. They have a dual coil atomizer. The threading on this .3ml and .9mm glass cartridge is with industry standard 510 thread. This works amazingly well with Med-ePen batteries and Med-ePen kits.
