Brush pens were first sold as Japanese writing pens, they are a great convenience for cartoonists, comic book artists, pen and ink drawing fine artists and scrapbooking -best of all, they're easier to use than most of the mediums they function like!
Copic Multiliners pens are quick-drying, the ink is pigment based and waterproof and will not bleed or smear when used with Copic Markers
The nib is made from a hardwearing polyester that will last a long time
