Always cap the pen after use and ensure the cap snaps securely. Store with the cap on and keep away from direct heat or prolonged expose to air to minimize drying between uses.

The ink is pigment-based and designed for office, school, and artwork use. As with all markers, avoid ingestion and prolonged skin contact; use in a well-ventilated area and keep out of reach of small children.

Ideal use cases include architectural or mechanical drawings, technical diagrams, precise labeling, diagram annotations, inked sketches, and clean journaling with crisp lines.
