Frequently Asked Questions

Q: What type of ink does the UMN-515 use?

A: It uses Uni's premium black gel ink, which provides a smooth, consistent flow with rich pigmentation. The ink is water-resistant once dry, making it suitable for important documents and signatures.

Q: Can I refill the pen?

A: Yes! The UMN-515 is compatible with standard Uni UMR-85 gel ink refills (0.5mm), so you can keep using your pen for years without replacing the whole unit.

Q: Is the wood grip real wood?

A: Absolutely. Each grip is crafted from genuine natural wood — either light oak or dark walnut — meaning every pen has a slightly unique grain pattern. No two are exactly alike.

Q: Is this pen suitable for left-handed writers?

A: Yes. The smooth gel ink dries quickly, reducing smearing, which makes it a great choice for left-handed users as well.

Q: What is the difference between the oak and walnut versions?

A: The oak version features a lighter, honey-toned grip with a fine grain, while the walnut version has a deeper, chocolate-brown tone with a richer texture. Both offer the same writing performance — it's purely a matter of personal style.

Q: Is this pen good for everyday office use?

A: Definitely. The retractable mechanism, comfortable wood grip, and reliable 0.5mm gel ink make it ideal for signing documents, note-taking, and any professional writing task.
