What Does Rm Mean In Tattoo Needles

RM stands for Round Magnums and is commonly seen among different brands of tattoo needles. RM needles are larger in size and are split into two parts: the taper shank and the points. The taper shank is the part that fits into the tattoo machine and the points are the parts that actually produces the shading and outlining for tattoos. RM needles are often used for outlining and shading due to the larger size which helps produce long, thick lines.
