Features

• World's First Double Lock Pen Mechanism
  The TiButton® Double Lock features a unique locking button. The ink will not extend or retract until the locking button is pushed — making this the world's first pen with a true built-in safety feature.
• Completely Machined & Built In-House
  Every component — including the intricate mechanism — is crafted and assembled in our workshop using state-of-the-art five-axis machining centers, ensuring every detail meets the highest standards.
• Maximum Security for Active Carry
  The double lock feature is built for anyone who carries their pen in a duty vest, uniform, or active gear. The double-locking safety prevents accidental deployment — keeping your clothes and equipment clean.
• Smooth & Satisfying Operation
  The same smooth, tactile mechanism you love from NTI. Push the lock button, then click — the internal spring delivers a clean, confident deployment every time.
