Consistent flow
No skipping or blotching. The ink flows smoothly from the first stroke to the last drop. A reliable tool for professional work.

Perfect for intricate details
The 0.05mm tip is incredibly precise. I use these for my architectural sketches and the lines are consistently clean without any bleeding.

Solid everyday pen
Good for journaling and note-taking if you like very fine print. Dries instantly which is great for left-handed writers like me.

Great value for artists
Excellent pen for the price. The only reason I didn't give 5 stars is that the cap can be a bit tight to remove sometimes, but the line quality is superb.

My go-to for manga inking
I have tried many fineliners, but the STA 8050 offers the best control for hatching and cross-hatching techniques. Highly recommended.

Truly waterproof
I tested this with watercolors and the ink did not smudge at all. It holds up perfectly even when wet media is applied over it.
Q: Does the 0.05mm tip bend easily?
A: The tip is made of durable stainless steel. While it is sturdy, we recommend avoiding excessive pressure or dropping the pen to prevent damage to the ultra-fine point.
Q: Can I refill this pen once the ink runs out?
A: No, the STA 8050 is a disposable fineliner and is not designed to be refilled. We recommend recycling the barrel according to local guidelines.
Q: Is this pen suitable for use with alcohol markers?
A: Yes, the waterproof pigment ink is designed to resist bleeding when alcohol markers are layered over it, provided you let the ink dry completely first.
Q: Is the ink archival quality?
A: Yes, the pigment ink is acid-free, fade-resistant, and archival quality, making it suitable for long-term preservation of your artwork.
Q: What is the shelf life of the ink if I don't use it often?
A: If stored horizontally with the cap tightly sealed, the pen can last for several years without drying out. Always store it horizontally to maintain ink flow.
