Smooth and reliable
I've tried many fine liners, but Uni Pin is my go-to. The flow is smooth, no skipping, and the cap seals tightly so the pens don't dry out even if left uncapped for a few minutes.

Student essential
Bought these for my architecture class. They handle detailed drafting perfectly. The hexagonal barrel is a nice touch as it stops them from rolling off the desk constantly.

True black ink
The black is very deep and opaque, which looks great when scanning artwork. The 0.1mm is my favorite size for general outlining. Will definitely repurchase.

Great quality, wish there were more sizes
Excellent pens for technical drawing. The lines are crisp and dark. I only gave 4 stars because this specific set only has three sizes; I usually need a 0.5mm as well for broader strokes.

Perfect for intricate manga work
The 0.05mm tip is incredibly fine and consistent. I use these for my comic book inking, and the waterproof ink means I can watercolor over them without any smudging. Highly recommended for serious artists.

Good value set
Solid pens for the price. The 0.05mm requires a gentle hand, but once you get used to it, the precision is unmatched. Good for stippling techniques.
Q: Do these come with a carrying case?
A: This specific 3-piece set does not include a carrying case; they are packaged in a standard blister pack or box depending on the retailer.
Q: How long do the pens last if used daily?
A: Lifespan varies by usage intensity, but with daily moderate use, a single pen typically lasts several months before the ink runs out.
Q: Are these pens safe to use on photo paper?
A: Yes, these oil-based pens work well on most paper types, including photo paper, without bleeding or feathering.
Q: Can the ink be erased with a standard eraser?
A: No, the ink is permanent and waterproof once dry. It cannot be erased with standard erasers.
Q: Is the 0.05mm tip durable enough for rough sketching?
A: The stainless steel tips are durable, but the 0.05mm is very fine. We recommend using it for final inking rather than rough sketching to prevent tip damage.
