Warning: You will want this Brush Pen

Brandi York | May 8, 2017

Warning: Upon viewing this blog post you want a Gasenfude brush pen. This pen is a new addition to the Copic inking line.  Brandi York explores the possibilities this brush pen offers. (One of our marketing specialists adds VERY important notes in parenthesis.)


Like all of our Multiliner pens, the ink in the Gasenfude is Copic proof and waterproof on most surfaces. However, unlike the Multiliner brush nibs, the Gasenfude brush tip is made of individual nylon bristles that act more like a sumi-e brush. (Each nylon bristle will kiss your paper, as delicately or intensely as you wish.)

There are a variety of different strokes that you can achieve with this pen, depending on how quickly you make your strokes and at what angle you hold the pen. (Slowly or quickly? Oh so dynamic!)


Thin, narrow lines are achieved by holding the pen more upright, vertical to the page. Barely touching the tip to the paper creates thinner lines; pushing down a bit will spread the bristles, thickening the lines.

(You'll want to squiggle lines all day, every day, for the rest of your life.)


Like any brush-tipped pen, you can vary the line width while dragging the pen along by changing the angle at which you're holding the pen while making the stroke. (That feeling in your fingertips is the longing to Gas-en-fu-de.)


For textured strokes, use the pen on its side, to where it's almost parallel to the surface of the page. (How badly do you need textured brush strokes? You don't have to answer that. We know...)


Play around with these various techniques to get a feel for how different pressures and angles on the pen will change the stroke. Also, the speed at which you move the pen will change the texture of a stroke; faster strokes with be slightly more broken than slower strokes. (In love yet?)

Different papers will also affect the strokes; smoother papers will have less texturing from the bristles while rougher papers will give a more textured, broken look to the strokes.  (How is this not a romance novel?)

Using the different techniques with the brush tip, I sketched out a harbor scene. (Oh, things are getting serious now.)


Changing the angle of the pen changed the line weight and texture as I drew on different aspects of the scene. The strokes of the dock were more vertical while the water was utilizing the side of the brush. The hull boat was outlined in thin strokes and then streaked with the side of the brush. Faster strokes left less ink behind on the paper, creating more of a scumbling - or hit and skip of ink on the paper surface - effect while slower strokes left darker patches of ink.

Strokes varied according to the angles at which I held the pen, as well as overlapping similar strokes, like using the side of the brush over itself a few times to create more depth of texture in the water.

I let the piece dry for an hour. The longer, the better with brush pens, as they leave behind more ink than finer nibs. I then added a handful of colors to the piece, to help define objects and pop out aspects of the sketch. (OMG, ready now more than ever to make this dream a reality.)


I hope you find this as a good jumping off point to experiment with the new Gasenfude pen.  Final verdict? The Gasenfude is loads of fun for finished work, calligraphy, or just doodling!

Once upon a time, in a far away land, there was a young girl who grew up down the street from Disneyland. From 1992, and her first viewing of Beauty and the Beast, she began her long road as a portraiture artist and the life of a geek. More than 20 years and thousands of portraits later, Brandi's work has become a strange collection of fine art landscapes and florals, with the occasional en plein air piece, mixed with the geekier side of pop culture.
