1. It goes between 1 mm & 2mm so that would make it approximately 1.5mm
2. if you can’t draw a straight line with a pen or pencil, don’t try it with a ‘gun’
3. See #2 above about the straight lines & how long do you think it will take to shade a tattoo with a 3 needle? ( here’s a tip, needles are marked on the packaging they come in with exactly what they are, ie
3rl 5rl etc all the way up to about 18rl where the ‘rl’ part means round liner.
shaders are marked similarly but have the letters ‘rs’ = round shader.
Buying a tattoo machine without knowing the absolute basics is like buying a car with no driving experience, sooner or later someone is gonna get seriously fucked up.
use uncle google for tattoo tutorials, or just type a question in the YouTube search box, I’m sure something will pop up😉
Are you aware that you should use 2 machines, one for lining and 1 for shading as they run at different speeds and put the ink in differently
