Do they do touch ups of their work that wasnt done efficiently

I wouldnt trust the artist that did mine to do a touch up. Im just going to bite the bullet and go to another place to pay to either have it covered or attempt to fix the horrible job they did to my wrist. I actually wear a scrap of black cloth over my wrist to hide it, its that embarrassing

I think it depends on the artist..but usually free touch ups. I am pleased with the work Joshua did on my tat. Has healed nice and needs nothing else.

Possibly
