Perfect for Manga Inking

These pens are absolutely fantastic for inking manga panels. The line consistency is incredible, and the 0.05mm tip allows for extremely fine details without skipping. Highly recommended for any serious artist.

No Bleed Through

I was worried about bleed-through on my sketchbook, but these water-based inks dry instantly and stay on the surface. Perfect for double-sided pages.

Student Favorite

Bought this set for my graphic design course. The color-coded caps make it easy to grab the right size quickly during timed exercises. Very durable construction.

Consistent Flow

Unlike other brands I've tried, these maintain a consistent ink flow from the first stroke to the last drop. Essential for long drawing sessions.

Architectural Precision

I use these for architectural sketches and technical diagrams. The ink flows smoothly, and the lines are crisp and black. They haven't clogged even after months of daily use.

Great value set

Excellent quality for the price. The only reason I didn't give 5 stars is that the 0.8mm pen felt slightly scratchy on my textured paper, but the finer tips are flawless.

5 FAQ

Q: Are these pens refillable?

A: No, the STA Fine Liner 8050 series is designed as a disposable unit once the ink is depleted to ensure consistent line quality throughout its life.

Q: Is the ink waterproof?

A: The ink is water-resistant once fully dried, making it suitable for light washes with watercolors, but it is not completely waterproof if submerged.

Q: Do you sell individual refills or single pens?

A: Currently, the 8050 model is only available as a complete 8-piece set. Individual replacements are not sold separately.

Q: Can these be used on fabric?

A: While they work on many surfaces, they are optimized for paper. For fabric, we recommend heat-setting the ink, though permanence may vary compared to dedicated textile markers.

Q: What is the shelf life if left uncapped?

A: We strongly advise capping the pens immediately after use. If left uncapped for more than a few minutes, the fiber tip may dry out and become difficult to revive.
