Good but takes practice

The pen is high quality, but if you press too hard, the tip can splay a bit too much. Once you get the hang of the pressure sensitivity, it produces beautiful natural strokes.

Great for small signatures

I bought this specifically for signing artwork and small calligraphy projects. The control is excellent, and the ink flows smoothly without blotching.

Perfect for manga inking

The flexibility of this brush tip is incredible. I can go from hair-thin lines to bold shadows just by changing pressure. The brown ink adds a nice vintage feel to my sketches.

Waterproof claim is true

I accidentally spilled water on my drawing, and the brown lines didn't smear at all. Truly waterproof pigment ink as advertised. Highly recommend for wet media users.

My new favorite travel pen

Compact and reliable. The cap seals tightly so I don't worry about it drying out in my bag. The sepia tone looks wonderful in my travel journals.

Solid choice for professionals

I use these for final inks on my comic pages. The only reason for 4 stars instead of 5 is that I wish the ink reservoir was slightly larger for longer sessions.
