The Copic Multiliner SP is a waterproof, acid-free, archival quality pigment based pen which holds black ink that is resistant to UV light. The pen is bleed-proof when used with alcohol-based markers and the ink is also photocopy safe. Made from a durable brushed aluminium, the nibs are encased in solid metal sleeves that not only protects but also ensures a precise and consistent line width. The Multiliner range of pens were developed for graphic artists, industrial designers and architects. As the cartridges and nibs can be replaced, this allows for lifetime use.
