D1 Moon Cage combines sculpted openwork metal with a restrained monochrome presentation.

Moon Cage Openwork and Chinese Ornament

D1 uses a sculpted steel shell with continuous openwork patterns across cap and barrel. Moon imagery, auspicious Chinese motifs and polished trim create a formal visual identity suited to desk use, executive gifting and collectible display.

• Continuous openwork panels create depth across the closed pen.
• Moon and ornamental references support the Moon Cage story.
• Polished rings, clip and section provide crisp structural contrast.
• Silver, glazed blue and black treatments address different preferences.

The coordinated cap and barrel maintain the openwork motif from every viewing angle.

Steel Shell and Smooth Openwork Edges

The supplied specification confirms a steel outer shell. Quality review should focus on uniform openwork edges, surface polishing, secure clip alignment and consistent cap engagement. Interior material details are not stated and should be verified against the approved sample.

• Inspect every openwork edge for burrs, distortion or sharp contact points.
• Check polished surfaces for scratches, pits and plating variation.
• Confirm clip alignment, cap engagement and section transitions.
• Compare each variant under neutral production lighting.

Balanced Metal Feel for Professional Use

The Professional Fountain Pen is designed for users who want decorative craftsmanship with a stable working weight. At approximately 23.5 g uncapped and 40.5 g complete, D1 should be tested uncapped first to establish the preferred balance for notes, signatures and longer writing sessions.

• Begin uncapped to evaluate the 23.5 g working weight and grip position.
• Use light pressure so the soft nib can recover naturally.
• Rotate the piston smoothly and stop when resistance increases.
• Protect the openwork shell from impact and abrasive pen cases.

D1 is presented as a practical writing instrument with a distinctive professional appearance.

The black presentation gift set is shown with ink; pen-only SKUs are labeled without ink.
