Frequently Asked Questions

Q: What types of models can I use this panel line pen on?

A: This panel line infiltration pen is suitable for a wide range of plastic model kits including Gunpla (Gundam), military vehicles, aircraft, sci-fi ships, dioramas, and architectural models. It works best on plastic surfaces with recessed panel lines.

Q: How do the 5 nibs differ from each other?

A: The 5 interchangeable nibs are designed to accommodate different panel line widths and detail depths, allowing you to work on both fine, narrow lines and slightly wider grooves with the same pen body for maximum versatility.

Q: Is this pen easy to use for beginners?

A: Yes! The panel line pen uses a capillary infiltration method — simply touch the nib to a recessed panel line and the ink flows in automatically. No scrubbing or heavy pressure is needed, making it beginner-friendly while still delivering professional-quality results.

Q: How do I clean up excess ink after lining?

A: Any excess ink that bleeds outside the panel lines can typically be wiped away with a cotton swab lightly dampened with appropriate model thinner or rubbing alcohol, depending on the surface coating. Always test on a small area first.
