Worried about heavy metals? With these all-ceramic vape cartridges you will never have to worry about heavy metals in your vape cartridges again! That’s because no part of the oil will touch any metal, the entire vape cartridge is made out of ceramic (ceramic mouthpiece, ceramic rod, and ceramic coil) the only metal is underneath the cartridge that screws into the top of a vape battery. Note: The 510 thread is metal but does not contain any heavy metals like zinc or lead.
