Yup. There is, a tattoo gun uses the needle to pierce you're skin and inject permenant ink.
The tattoo needle should stick out of the gun (tube tip) about 1 to 2 millimeters when at rest, and slightly more when the machine is running due to vibration.
just a little bit so you can see it
The thickness of a dime from tip to needle points, that's without the machine running. Tip: we don't call them "guns" they are "machines", novices who don't know better call them "guns".
The size of the needle and the size of the tip should match unless you are using bugpin needles, in which case the tip should be two sizes smaller than the needle.
Never get any piercing with a gun-style piercing machine no matter what. Gun-style piercing machines cause trauma, unnecessary damage, and scar tissue around the piercing that would not happen when proper equipment (a bevel-tip hollow piercing needle) is used.
he dosent have one
no she dosn't but she might soon.
Needle.
A point.
Probably a needle because a gun is more likely to cause an infection and it's better if a needle is used.
On a center fire gun, rounded tip. On a rimfire gun, the tip is shaped a bit like the tip of a screwdriver blade.
Of coarse you can. I got mine done when I was eight. It just depends on your parents. And here's a tip, Never get it done with a needle gun. Cause they can cause infection.
