What is the Copic Gasenfude?
It’s a brush pen from Copic, the Japanese alcohol-marker brand, with a nylon brush tip and black pigment ink. Copic Japan calls it a brush-type pen that fits the hand and can be used with Copic markers without bleeding.
The name is Japanese: 画箋筆 (gasen-fude), roughly “drawing-paper brush.” Copic describes the tip as moderately firm with a soft point, so one pen draws both fine lines and bold strokes.

Not stated
The 205 mm size Copic lists matches a Swiss retailer’s package length, so it most likely describes the package, not the pen.
A 9 mm brush flexes for broad strokes and comes back to a point.
Can you color over the Gasenfude with Copic markers?
Yes: Copic says that once the ink dries, it won’t bleed into Copic markers and won’t smear when you color on top. Copic Japan says it uses the same water- and alcohol-resistant pigment ink as the Copic Multiliner.
That makes it a brush partner for the Copic Multiliner and Copic Sketch markers: ink with the brush, then color with alcohol markers.
How do you draw with the Gasenfude?
Hold it at a low angle and vary the pressure: light for hairlines with the point, heavier for broad strokes with the belly of the brush. Opus Art Supplies says the long, flexible bristles also give a dry-brush effect, while the fine point handles detail.
Opus recommends it for hand lettering, calligraphy, comic art and traditional brush work. Copic shows it inking botanical sketches and architecture on its US page.
Because the ink is waterproof once dry, Copic says, you can paint over the lines with watercolor or color them with alcohol markers. Let the ink dry fully first, and recap the pen after use so the brush doesn’t dry out.
For lettering practice, smooth paper keeps the edges crisp. On textured watercolor paper, a fast, light stroke breaks up into the dry-brush texture many ink artists look for.
How does the Gasenfude compare with other brush pens?
The Gasenfude and Pentel Pocket Brush have real nylon bristles; the Fudenosuke and Mangaka Flexible use firmer, solid tips that hold their shape.
If you want bristles you can refill, the Pentel Pocket Brush takes cartridges. Our best brush pens roundup compares more.

Frequently asked questions
How do you pronounce Gasenfude?
Gas-en-fu-day, per Opus Art Supplies. It's written 画箋筆 in Japanese: gasen is a kind of drawing paper and fude means brush.
Can you use Copic markers over the Gasenfude?
Yes. Copic says the dried ink won't bleed into Copic markers and won't smear when you color over it.
Is the Copic Gasenfude refillable?
No. Amazon's listing calls it disposable; Copic sells refills for its alcohol markers, not for the Gasenfude.
Is the Gasenfude waterproof?
Once dry, yes: Copic says the pigment ink becomes waterproof when dry, so you can paint watercolor over the lines.
Is the Gasenfude good for calligraphy?
Opus Art Supplies recommends it for hand lettering, calligraphy, comic art and traditional brush work; its long bristles also make dry-brush strokes.
What paper works best with a brush pen?
Smooth paper, such as Bristol or marker paper, keeps nylon bristles from fraying and gives the cleanest edges; textured paper gives a dry-brush look.
Who makes Copic?
Too Marker Products Inc. of Tokyo; Too Corporation Americas sells Copic in the US.
