Everyone who is anyone knows that this is the BEST ink out there, and that the goto inks of old are being watered down... I don't really want to mention them here, but I shouldn't have to. Quantum truly has created some outstanding inks that are easy to mix, and go right in! The pigments are super concentrated, WILL NOT FADE in 6-12 months like most inks. Really Nice, Guys!!! Thanks for the super fast order, and everything else Phil!!!
