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. ## Copic Gasenfude specs **Copic lists the price and a size of 205 × 47 × 12 mm; retailers give the brush dimensions.** Copic doesn't publish the pen's own length. | Spec | Copic Gasenfude | |---|---| | Tip | Nylon brush, 9 mm long, 3.1 mm at the base (Opus Art Supplies) | | Ink | Black, water-based pigment, same as the Multiliner (Copic) | | Once dry | Waterproof and alcohol-resistant (Copic) | | Refillable | No, disposable (Amazon) | | Size listed | 205 × 47 × 12 mm (8.1 × 1.9 × 0.5 in), Copic | | Japan list price | ¥506 (about US$3.20) with tax | | GTIN | 4511338049174 (Amazon) | | Made in | 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. ![The Gasenfude's nylon brush drawn to scale: 9 mm long and 3.1 mm wide at the base, next to a 0.3 mm fineliner point](https://stationerytimes.com/images/copic-gasenfude-tip.svg) *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](https://stationerytimes.com/guides/copic-multiliner/) and [Copic Sketch](https://stationerytimes.com/guides/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.** | | Copic Gasenfude | [Pentel Pocket Brush](https://stationerytimes.com/guides/pentel-pocket-brush-pen/) | [Tombow Fudenosuke](https://stationerytimes.com/guides/tombow-fudenosuke/) | [ZIG Mangaka Flexible](https://stationerytimes.com/guides/kuretake-zig-cartoonist-mangaka/) | |---|---|---|---|---| | Tip | Nylon bristles | Nylon bristles | Elastomer, hard or soft | Flexible POM | | Ink | Pigment | Pigment, cartridges | Pigment | Pigment | | Refillable | No | Yes | No | No | | Price band | $$ | $$ | $ | $ | If you want bristles you can refill, the Pentel Pocket Brush takes cartridges.

Copic is a brand of Too Marker Products Inc. of Tokyo. ## Frequently asked questions ### How do you pronounce Gasenfude? Gas-en-fu-day, per Opus Art Supplies.
