Before first use, test on scrap paper to confirm line density. Cap it when not in use to prevent drying, store upright or horizontally as recommended, and gently wipe the nib if any ink smudges. If a line starts skipping, draw a few light strokes on scrap paper to re-wet the nib.

The pigment-based ink is non-toxic and designed for writing and drawing. It’s acid-free and archival, intended for long-term storage of artwork and documents. Keep away from ingestion and supervise young children around drawing instruments.

This pen performs well on standard sketchbooks, technical pads, and planning papers. It may show minor feathering on very glossy or non-porous surfaces; for best results, use on smooth, slightly porous papers designed for ink drawing.
