Based on the length of the pen holder, the dividing line processed by precision cutting creates a rational aesthetic of the unit composition and subtly hides the parts such as the pen holder, pen cover, and rotating mechanism in the dividing line.

Its compact size is matched with the lightweight aluminum alloy material and strong characteristics, which meets the demands of light and portable use.
