Prison tattoo is a common occurrence in prisons worldwide. I for one do not oppose to any type of tattooing and always doing my research of different procedures of making Art.
The practice of creating and displaying tattoos in a prison environment does vary but I will show the most common. This is just to give you an idea, there are some amazing tattoo artists out there so we have no need to do our own. Lack of proper equipment and sterile environments lead to health risks such as infection or disease (hepatitis, AIDS) from contaminated needles.
