NPM Patented Needle Theory

NPM Patented Needle Theory

NPM offers a variety of needles—choose any thickness, length, structure, tip type and material.

Generally, there are two types of tips: a long tip or a short tip. Needles with a long tip are more suitable for creating
lines, while short tipped needles are better suited for filling in areas and shading.

For acupuncture, tattoo art or permanent makeup, there are five types of needle thickness:

  • Needle #6 (4 times zero) is 0.22 mm thick
  • Needle #8 (3 times zero) is 0.25 mm thick
  • Needle #10 (2 times zero) is 0.30 mm thick
  • Needle #12 is 0.35 thick
  • Needle #14 is 0.40 thick

There are an unlimited number of structure combinations, but these are the most commonly used:

  • Structure A: Flat structure – This is a structure where all the needles are connected close to one another and at the same height.
  • Structure B: Magnum structure – The needles are connected close to one another and at the same height, but the second and fourth needle is raised slightly.
  • Structure C: Double stack – Three needles are connected in a flat manner, with two flat needles on top, to create two levels of needles.
  • Structure D: Japanese structure – Needles are connected in a flat manner where the middle needle is higher than the two needles on the sides to create a graduated structure.
  • Structure E: Diagonal structure – Needles are connected in a graduated fashion where every needed is lower than the one next to it.
  • Structure F: Circular structure – Needles are connected together to create a structure where there is one needle in the middle surrounded by four needles.
