The Copic Multiliner SP fineliners are permanent fineliners with archival, lightfast and permanent ink which is waterproof and photocopy safe.
These pens are economical and long lasting thanks to the ability to change the refils and the nibs, rather than buying new fineliners each time. There are 12 colours of ink refills available.
Copic Multiliner SP nibs come in 10 sizes, and the finer nibs are packaged in packs of 2, as the very fine nibs wear out quickly and will need replacing more often.
The nib sizes available are: 0.03, 0.05, 0.1, 0.2, 0.25, 0.3, 0.35, 0.5, 0.7 and a Brush nib. The brush nib is made from foam, making it very soft and able to produce lots of different line widths depending on the pressure used.
Copic also have a nib changing tool, which is especially useful for the finer nibs, which helps in the easy removal and replacement of nibs without damage or mess.
