Xunmu Hand-Engraved “Lunar Galaxy” TACTICALGEEK × Hidetoshi Nakayama Gennai Pen SL01 – Bronze & Copper Inlay

Product Description

A special hand-engraved interpretation of the TACTICALGEEK × Hidetoshi Nakayama Gennai Pen SL01, individually customized by Xunmu.

Inspired by the Moon and the galaxy, the stainless steel body is transformed through intricate hand engraving, with celestial bodies and orbital details accented by individually inlaid bronze and copper elements.

The contrasting metals introduce subtle variations in tone across the stainless steel surface, bringing a celestial dimension to the distinctive mechanical character of the original Gennai Pen.

At its core remains Nakayama’s signature Telegraph Key–Style Lever Mechanism, turning the mechanical structure itself into part of the writing experience.

Measuring approximately 96 mm in length and weighing approximately 64 g, the SL01 is compatible with the SCHMIDT P900M and standard G2-size refills.

A distinctive fusion of hand engraving, metal inlay, and mechanical design.
