This is the most beautiful black ink I have ever used. The copper sheen is amazing!!! You have to see it in person to believe it. It lights up transformer boxes and coated slaps like eggshells. I use it in a mini crusher and oh god, oh god! Another nifty thing I like to do with it is mix it with an ink that fades like OTR and the whipsy tags that are left after the lighter ink fades from the sun is... OOOOh and it writes so smooth. It is utterly orgasmic. This is the ink you need for lonely days and nights.
