Truly Waterproof
I tested this with watercolor washes over the ink lines, and it held up perfectly without running. The self-controlled ink flow means no messy blobs.

Good for detailed work
Excellent for fine details in anime drawing. The grip is comfortable for long sessions. I wish it came in a multi-pack for better value, but the quality is there.

Great value for students
As an architecture student, I need precise lines for my drafts. This pen delivers clean edges without bleeding through standard sketchbook paper. The only downside is the cap can be a bit tight initially.

Best pen in this price range
I switched from a much more expensive brand to Dianshi and honestly can't tell the difference in performance. The quick-dry feature is a game changer for left-handed drawers like me.

Perfect for Manga Inking
I use these pens daily for my comic strips. The line consistency is incredible, and the ink dries fast enough that I don't smear when shading. Highly recommended for artists.

Smooth and Reliable
The needle tip glides smoothly across the paper. I've been using it for technical illustrations for three months, and it hasn't skipped once.
Q: Does the ink fade over time?
A: Our liquid ink is formulated to be archival quality and lightfast, ensuring your drawings remain vibrant and dark for years.
Q: Is this pen refillable?
A: No, the Dianshi DS-704 is designed as a disposable unit to ensure consistent ink flow and tip precision throughout its lifespan.
Q: Can I use this on glossy photo paper?
A: While it works on many surfaces, we recommend using it on standard drawing paper or bristol board for best results. Glossy surfaces may increase drying time.
Q: What is the exact line width of this pen?
A: The DS-704 model features a 0.4mm needle tip, ideal for medium outlining and general sketching tasks.
Q: How do I prevent the tip from drying out?
A: Always ensure the cap is snapped on tightly immediately after use. The air-tight seal is designed to keep the ink fresh between uses.
