How do prisoners make tattoo guns 😮

Ouch That would hurt

No bro I did tattoos in prison ink was not smeared onto the skin I put it in a toothpaste cap . The ink was made by burning Vaseline or hair grease and collecting the soot from it then mix it with shampoo or rubbing alcohol or medical soap for darker results. Never used button

Ingenuity. They build them from simple parts.
