Archival pigment ink is designed to resist fading over time and to stay sharp after handling. This pen’s ink is waterproof once dry and resistant to smudging, making it suitable for long-lasting diagrams, notes, and lettering.

It performs well on standard paper types such as planners, cards, and grid paper, with reduced feathering. For very smooth or coated papers, test a small area first to ensure the line remains crisp and the ink doesn’t lift.

The textured barrel provides a steady, comfortable hold, helping you maintain consistent pressure and smooth, precise lines, especially at tight corners or along edges.

It’s ideal for diagrams, technical drawings, architectural notes, labeling, callouts, careful lettering, journaling, and any project that benefits from crisp, long-lasting lines.

Keep the cap on when not in use to prevent the nib from drying. Use light, steady pressure for clean lines, and allow ink to dry before touching. When working with rulers or stencils, let the tip glide without heavy scraping to avoid damage.

Yes. The ink is archival-grade and water-resistant once dry, making it suitable for long-term documents, drawings, and notes that you want to preserve over time.

The 0.3 mm red offers the same line width and archival performance as other 0.3 mm Uni Pin pens, with color choice affecting readability and emphasis in your diagrams. For variety, you can also choose 0.3 mm in black or blue, or try 0.5 mm for thicker lines.

0.3 mm pens produce finer, more delicate lines ideal for detailed diagrams and small lettering. 0.5 mm pens create bolder lines that stand out more and can be better for larger labels or surface textures. If you’re unsure, start with 0.3 mm for precision and move to 0.5 mm for stronger emphasis as needed.

The metal-clad tip is designed to work smoothly with rulers and stencils. Use a light touch, keep the ruler firmly in place, and let the ink flow without forcing the pen. Lift and reposition as needed to maintain straight, crisp edges.
