Great quality, slightly thick for details
Excellent build quality and truly waterproof as advertised. However, 1.0mm is a bit too thick for fine architectural details, but perfect for main structures.

Reliable and affordable
These pens last a long time even with daily use. The cap seals tightly so the ink never dries out prematurely.

Perfect for bold outlines
The 1.0mm tip is exactly what I needed for my comic book inking. The line is consistent and the ink flows smoothly without skipping.

Easy to hold for long sessions
The barrel design is comfortable and prevents hand fatigue during long drawing sessions. Highly recommended for hobbyists.

My go-to for watercolor underdrawings
I love that the ink doesn't bleed when I paint over it with watercolors. It stays crisp and clean every time.

Solid performance
Very smooth writing experience. The only reason for 4 stars is that I wish the set came with a variety of sizes instead of just 1.0mm.
Q: Is the 1.0mm tip made of metal or felt?
A: The tip is a durable plastic fiber tip designed to maintain its shape and provide a consistent line width over time.
Q: Are these pens safe to use on photo paper?
A: Yes, the pigment ink is acid-free and safe for use on most photo papers and archival materials without causing damage.
Q: Do these pens work well on dark paper?
A: Since these specific pens contain black ink, they will not show up on dark paper. You would need our white gel pen series for dark surfaces.
Q: What is the shelf life of the ink if unopened?
A: Unopened pens have a shelf life of approximately 3 years from the manufacturing date when stored in a cool, dry place.
Q: Can the ink be removed with an eraser?
A: No, once the waterproof pigment ink dries, it is permanent and cannot be erased. We recommend using pencil for initial sketches before inking.
