NPM Patented Needle Technology
NPM rollers are made from the finest 316L ROSS stainless steel. This is the same material that is licensed for medical use and commonly found in stents.
NPM roller has 56 needles, each needle is 0.25mm wide and 1.3mm long. The roller has 4 discs, each containing a set of 14 needles. It is important to understand that the roller is not just needles stacked on a roller. The needles distance and density from one another provide perfect imitation of natural scalp follicles.
NPM needles are also one integral unit. This means the needle and the cover body are one, ensuring the needle will remain aligned at all times during operation.
Needles are designed to absorb color and to release it only when the needle touches the skin. This reduces spills and ensures a clean, professional treatment. And, when the motor stops, the needle remains inside the unit.
The needle and the roller are for one-time use to meet the sterilization standard for medical treatment. For more on needles, click here.
