Seen 1205 RL and wondered what the numbers and letters mean? Like paintbrush tips, different shapes suit different marks-though tattoo needles pierce, not brush. In common coding, 12 typically means 0.35-millimeter diameter; 05 means five needles, not twelve. That's the key: letters show grouping and use. RL lines; RS shades small areas; RM suits broader shading or color. Typical uses, not strict limits. All move up and down, placing pigment in the dermis; 1205 means five 0.35-millimeter needles.
