Dominant Industry MM Pad – Fountain Pen Nib Thickness Gauge (Acrylic)

Precision, after all, is part of the pleasure.

The Dominant Industry Measure My Pen MM Pad is an elegantly simple yet remarkably clever tool for fountain pen enthusiasts and calligraphers who prefer certainty over guesswork. As the first of its kind, this transparent acrylic gauge allows you to measure both your nib’s thickness and the exact line width it produces on the page.

Simply place the pad over your writing and read the result with clarity. No more second-guessing whether that nib is truly Fine, Medium or something in between. You see the measurement. You know.

Crafted from durable, fingerprint-resistant acrylic, the MM Pad features finely printed silver measurement lines that remain clear and legible in various lighting conditions. Its compact form slips easily into a pen case or desk drawer, ready for ink testing, collection cataloguing or ensuring consistency in calligraphy practice.

It even doubles as a mini ruler — because a well-designed tool rarely confines itself to a single task.

For writers who appreciate nuance, detail and control, the MM Pad turns curiosity into confidence.
