Truly waterproof

I tested these with watercolors and the black lines did not smudge or run at all. Excellent quality for the price point.

Great value for students

As an architecture student, I go through a lot of liners. These hold up well during long drafting sessions. The only reason for 4 stars is the brush tip is slightly stiffer than I expected.

Perfect for my manga projects

These pens are incredibly consistent. The ink flows smoothly without bleeding through my standard sketchbook paper. The dual tips are a game changer for varying line weights.

Smooth and reliable

No skipping or blobbing. The grip zone makes them comfortable to hold for hours. Highly recommend for technical illustration.

Good set overall

The fine tips are very precise. I wish the set included a 0.2mm option, but the 0.3mm works well enough for most of my detailing work.

Best purchase this year

I switched from a more expensive brand and honestly cannot tell the difference in performance. The caps seal tightly so the pens don't dry out.

5 FAQ

Q: Are these pens safe to use on photo paper?

A: Yes, the oil-based ink is generally safe for photo paper, but we always recommend testing on a small corner first as coatings vary by manufacturer.

Q: What is the shelf life if I leave the cap off accidentally?

A: If left uncapped, the pen may dry out within a few hours. Always ensure the caps click securely into place after use.

Q: Can I refill these pens once the ink runs out?

A: No, the Languo Dual-Tip Liners are designed as disposable units and cannot be refilled.

Q: Is the ink archival quality?

A: The ink is fade-resistant and waterproof, making it suitable for long-term storage, though we do not officially certify it as archival grade for museum purposes.

Q: Do the brush tips fray easily after extended use?

A: The brush tips are made from durable synthetic fibers designed to maintain their shape. Avoid pressing too hard to ensure longevity.
