Needles are premade, sterilized by E.O. gas in individual blister packs. Magnum tattoo needles are specifically designed to produce finer control over tattoo ink during the tattoo process. The needle points are arranged in two or more rows and sometimes are curved to present a smoother tattooing experience for both artist and sitter. Using a magnum tattoo needle on a standard tattoo machine is no different than using any other tattoo needle--machine set-up and use remains the same.
