Key specs include a high-opacity white gel ink, a 1.0 mm bold tip for prominent lines, smooth ink flow for clean lettering, and suitability for dark papers, photos, and craft boards. It’s ideal for dense fills, with a note to allow extra dry time to prevent smudging.

Remove the cap and write on dark papers, photos, or craft boards to create bold highlights. For dense fills or large solid areas, give the ink a bit longer to dry to avoid smudging. When finished, recap the pen to preserve ink life.
