Frequently Asked Questions

Q: What makes this a "double-line" gel pen?

A: The double-line gel pen features a specially engineered tip that draws two parallel lines simultaneously in a single stroke. This creates a distinctive, structured line effect ideal for architectural design, decorative note-taking, and artistic illustration.

Q: Which tip size should I choose for architectural drawing?

A: For fine architectural detail and technical linework, the 0.1mm tip is perfect. The 0.3mm is great for medium-weight lines and annotations, while the 0.5mm suits bolder outlines and emphasis lines. Purchasing the 3-pack gives you all three sizes for complete versatility.

Q: Is the ink waterproof or smudge-resistant?

A: These gel pens use black gel ink that dries quickly to minimize smudging during writing. For archival or watercolor projects, we recommend testing on your specific paper before full use.

Q: Can beginners use these pens for art and calligraphy?

A: Absolutely! The smooth, consistent ink flow makes these double-line gel pens accessible for beginners and seasoned artists alike. They are especially popular for bullet journaling, hand lettering, and creative note-taking styles.
