I (and others) love having this on hand...
It is the best for diluting a color, especially when doing a black and gray tatuaje
Or tattoo!
When doing shade work on a "black & grey" piece.
I only get/have black and grey tattoos.
All you need is a "six round" needle for outlines, detail. And a twelve round for shading. High quality black ink, and witch hazel. You can do excellent tattoos with that
Or a flat 8 can be used for everything, you need some skill to do a whole tattoo with just that needle, great for shading, not commonly used for outlines or detail, but if you have the skill, you can angle the machine and use the edge for all work. A nice needle to have on hand, for it's diversity, in case you run out of other neddles, and don't have an autoclave.
