T-Tech magnums are weaved by way of a flat needle to allow for better ink dispersion while tattooing and have shorter needle points at the sides, making tattooing smoother and causing less damage to the skin. These curved magnums are #12 (0.35mm) in diameter with a regular 1.8mm taper. Round mags are great to colour pack large areas for tattooing, shading medium and large areas, as well as blending. Straight mags are used a lot for traditional tattoos.
