to illmate, don't buy any of these ink they suck balls trust me! they look cool 'cuz they're the best seller. but when you use it, the ink spreads on the wall like a marker would do on a paper, so when you write on a wall at first it looks cool but then it spreds soooooooo much that your name becomes unreadable. Now that I said this, you choose either to listen to what I said or to try it yourself. anyway Nero and Corio=shitty ink.
I prefer to pay a little more and have a dope grog or OTR ink, one dope ink is the Hot Chocolate from OTR. It's really powerful and even after being buffed you'll see a ghost of your name :) or you can also add some blue or violet FX to your ink so that when you get buffed, the same thing happens like the HotChocolate ink
