0.3 mm tip for micro-detail work, archival pigment ink that is water-resistant and fade-resistant, low bleed to minimize feathering, a textured grip for better control, and a metal-clad tip that works neatly with rulers.

Yes. The archival pigment is designed to be water-resistant and resistant to fading, helping important diagrams and notes stay legible over time.

Hold the pen with a relaxed grip and apply light, controlled strokes. Use a ruler or template with the metal-clad tip for straight lines, and test on scrap paper if you’re working on a new surface.

Yes. The pen is formulated to minimize bleed on standard paper. For the best results, test on a sample page and avoid pressing too hard on very thin paper.

Absolutely. The 0.3 mm tip provides sharp edges, and the textured grip helps maintain accuracy when drawing tight corners or small labels.

Handle with typical care for writing instruments. Keep the cap on when not in use, store away from children, and avoid ingesting the ink. The pigment-based ink is designed for archival use and long-term readability.

It performs well on planners, grid pads, and sketchbooks with standard-weight paper. For very thick or very thin stock, test first to ensure the line quality and reduce bleed.
