Products Description
D5 brings decorative metalwork and a working piston mechanism into one substantial writing instrument. A Hongdian No. 35 nib and B3 feed form the writing unit, while the rear control operates the internal reservoir. Color, nib grade, ink bottle, case contents and all commercial details remain order-specific and should be recorded in the signed specification.

The D5 uses a dark metal body, repeating measurement bands and sculpted historical motifs.
PRODUCT SPECIFICATIONS
Dimensions in this section follow the supplied D5 drawing and should be treated as working references. Hand measurement can produce small differences, and raised metal surfaces change appearance with the direction of light. Final acceptance should compare the production pen with the approved sample, including relief clarity, piston action and writing result.

APPEARANCE AND POSITIONING
A Metal Narrative Based on Qin Order and Measurement
The D5 body reads like a sequence of small historical panels. Repeated rings suggest standards and measured order; sculpted fields introduce birds, mountains, currency and defensive architecture. These elements are separated rather than crowded together, so the eye can move from cap to barrel and finally to the tripod-shaped end. A shared metallic framework keeps the many references visually connected.
- The dark version strengthens shadow inside the relief and gives the pen a museum-like character.
- Red inserts create a ceremonial accent without changing the disciplined body structure.
- Green with gold-toned details offers a warmer interpretation for collectors and presentation orders.
- Finish, pattern alignment and motif clarity should be approved with a physical sample.
PRODUCT BREAKDOWN
The decorative guide identifies the xuanniao bird, mountain pattern and related Qin design elements.Cap Crown Clip Barrel Grip Nib Feed and Piston
Reading the pen from top to bottom reveals both its decoration and its function. The cap holds the long clip and the first group of relief symbols. Measurement-inspired bands continue across the barrel, followed by an extended grip and the No. 35 writing unit. At the back, the differential piston control completes the silhouette and manages the bottled-ink reservoir.

BUILD QUALITY
Relief Engraving and Repeating Measurement Bands
D5 quality is determined in the small recesses of its metalwork. Lines must remain open and legible, band edges should look deliberate, and adjoining sections should meet without interrupting the pattern. Inspection therefore needs both normal viewing distance and close light from several angles. The piston, cap and nib must also operate smoothly so the elaborate surface does not distract from basic writing reliability.
- Inspect relief for incomplete lines, rough edges, residue and inconsistent depth.
- Check that repeating bands remain square to the body and meet without obvious offset.
- Verify clip alignment, cap engagement, piston movement and nib centering.
- Review colored panels for scratches, bubbles, uneven tone and loose edges.
- Use a fitted insert so metal relief cannot rub against the ink bottle or hard accessories.
Close views show the Qin authority, ruler, measure, currency and seal-script references arranged as barrel bands.
WRITING PERFORMANCE
Number 35 Nib and B3 Feed
Hongdian pairs the second-generation No. 35 nib with its B3 feed for this model. The combination is intended for controlled writing rather than exaggerated flex. Because perceived smoothness, ink delivery and line size change with nib grade, paper and writing angle, approval should include actual handwriting with the proposed ink. The 32 g complete weight gives D5 a firm, deliberate presence in the hand.

Black-dragon relief, a tripod-inspired tail cap and Great Wall linework continue the historical narrative.
Balance and Daily Handling
Begin testing with the cap removed and adjust the fingers along the 28.50 mm grip until the decorative steps remain clear of the hold. Let the nib travel under its own weight. For a realistic comfort check, write more than a short signature and compare the balance after several minutes, especially if the buyer normally uses lighter pens.
- Check first-stroke start-up after the pen has rested capped.
- Write repeated horizontal, vertical and curved lines to review continuous flow.
- Confirm nib alignment, feed position and line consistency with the approved grade.
- Operate the piston several times with water before the first ink fill.
USE INSTRUCTIONS
A green-and-gold D5 view accompanies the supplied dimensions and historical finish presentation.Differential Piston Filling Cleaning and Storage
Fill D5 only with fountain-pen ink and protect the work surface. Its two-stage piston procedure first clears the chamber and then draws ink while the entire nib and feed stay below the liquid. A small air space after filling is expected; forcing the rear control is not.
PREPARING AND FILLING
- Rotate the piston control counterclockwise to move the mechanism to its starting position and expel air.
- Place the complete nib and feed below the ink surface.
- Rotate the control in the filling direction slowly; repeat if necessary until the desired level is reached.
- Wipe the nib and section carefully before closing the pen.
WRITING AND CLEANING
- Use light pressure, keep the cap closed between sessions and protect the nib from impact.
- Flush the reservoir, feed and nib with clean, cool water before changing ink colors or long storage.
- Do not force a resistant piston or use abrasive and corrosive cleaners on the metal relief.

The photographed set places D5 in a fitted case beside a separate 60 ml bottle of non-carbon ink. That image is a configuration reference, not a substitute for a packing list. The quotation should state the selected pen finish, nib, bottle, ink color, instructions, insert and outer packaging so the Collector Fountain Pen story is matched by precise order information.
