Machined for the hand,
not the assembly line.

Most styluses are injection-molded plastic cylinders housing generic digitzers. We took a different approach.

The Interface Pen chassis is CNC-machined from a single block of aerospace-grade 6061-T6 aluminum. This gives it the precise weight distribution of a drafting pencil and eliminates the hollow, resonant feeling common in consumer electronics.

The center of mass sits exactly 42mm from the tip—resting perfectly in the web of your hand to prevent fatigue during 12-hour modeling sessions.

The Problem

The lag you feel is real.

When you draw a fast stroke on an iPad or Cintiq, the line trails behind your pen tip by anywhere from 9 to 25 milliseconds. Your brain notices this disconnect.
