02 / PRINCIPLE

The case against decoration.

Most writing instruments interrupt the hand with steps, knurling, screw threads and branding bands. Monograph eliminates every transition.

The grip tapers continuously at 1.8 degrees into the nib collar, placing the mass directly over the distal phalanx for zero rotational fatigue.

TOL-01 Continuous profile

Zero threads or step-downs between barrel and grip.

± 0.005 MM

TOL-02 Friction cap seal

Hermetic magnetic air-lock prevents ink drying for 90 days.

0.02 BAR

TOL-03 Acoustic dampening

Internal brass core attenuates high-frequency vibration.
