One of the best selling tattoo cartridges on the US market. Vertix cartridges are made by the manufacturer FK IRONS, which we certainly do not need to introduce :) Vertix cartridges pride themselves on the very high quality of their Japanese blades. The needle in the cartridge is very stable, and the impermeable membrane guarantees safety for your tattoo machine. The plastic tip of VERTIX cartridges is long and transparent, which ensures absolute precision and clarity when tattooing. You will all notice the two holes on the cartridges and we find them here to prevent ink splashes. It is certainly necessary to mention the very good washing of the cartridges thanks to the modification of the material inside the cartridge.
