The NEEDLE FINE LINER (Purple) is the little sibling of the original Needle Cap. Its average spray width is 2mm-10mm (0,08″ to 0,39″) making it a finer version. It achieves sketchy rough lines that are ideal for highlights, small details or rendering. The spray width changes with the used distance to the object. For skinnier lines, spray from a closer distance. For fatter lines, spray from a further distance.
