The Nitecore NTP31 is a multifunctional pen featuring a bi-directional bolt action design to smoothly transition between selecting either the pen refill or the tungsten steel tapered tip.
The pen is ideal for everyday writing and uses a high quality Schneider gel ink refill for quick drying and fade resistant writing. With a stainless steel tip and an anti-skid thread the NTP31 is smooth and comfortable to use.
The tungsten steel tapered tip is suitable for emergency use, such as having to break a window. Tungsten steel ranks second only to the hardness of diamond, according to the Rockwell scale.
