Structures
1. The tactical end
The business end can help holders defend themselves in emergency by puncturing an attacker.
2. The writing end
The tactical pen also functions as a regular writing instrument. A smooth writing experience is promised.
3. The pen body
a) Line of beauty
Its curved lines make it an aesthetic artwork, and the ergonomically tapered waist provides a firm grip and creates a lasting comfort in writing.
b) Anti-skid ability
Its wide threads enjoy a moderate coverage and a great position. Such ergonomic design can increase the friction and give a better grip without a hand abrasion.
4. The reversible cap
a) The pen cap can be snapped tightly on either end. Hence, users needn't twist it every time they want to write something. A convenient and constant use is achieved.
b) The flat cap top serves as a solid surface against a thumb to allow a secure and firm grip in emergency. And the thumb grip can help users stab enemies at a maximum force.
c) Fixed with two screws, the elastic clip can hang the pen tightly on your pocket.
5. Two ink cartridges
The tactical pen comes with 2 replaceable 424 pen refills. It is compatible with Parker styleG2 ballpoint refills, Fisher Space SPR4 pen refills and Rite in the rain No.37R ones.
