The NEEDLE FINE LINER (Purple) is the smaller sibling of the original needle cap. Its average spray width is 2mm-10mm (0.08" to 0.39"), making it a better version. It achieves schematic rough lines that are ideal for highlights, small details, or rendering. The spray width changes with the distance used from the object. For finer lines, spray from closer. For thicker lines, spray from a distance.

The NEEDLE CAP series earns its names due to its unique appearance. Unlike the dots that define the spray trajectory in standard caps, the needle cap has a hollow plastic tube that extrudes from the form of the round body, offering a paint trajectory at the spray output as if paint is sprayed through a needle. With an average spray width of 2mm to 10mm, the line produced by the NEEDLE FINE LINER (Purple) is similar to the STANDARD Cap with its dirty and raw characteristics. It is often used by street artists, urban artists, and studio artists to achieve splatters like application on small scales, the needle cap fits all female valve caps such as Montana GOLD, Montana BLACK, and Montana WHITE. The spray width changes depending on the distance used from the object being coated. For finer lines, spray from closer. For wider lines, spray from a distance. For larger splatter effects, reduce the pressure on the cap to activate it halfway.
