With their precise tips and high-quality inks, Copic Multiliners are favorite tools of artists, illustrators, and architects for meeting the rigorous demands of their inking work. Features:  

• Pigment-based, waterproof, bleed-proof, acid-free, and archival-quality ink.
• Compatible with Copic Markers.
• Photocopy-safe—this ink does not dissolve toner.

Note: Due to the fineness of its tip, this pen must be used with a light touch. Applying too much pressure may bend and damage the tip.
