Kuretake Bimoji Fude Brush Pen

The Kuretake Bimoji Fude Brush Pen is designed around the idea of “Bimoji,” meaning beautiful lettering. It is made to imitate the visual feel and weight of a traditional calligraphy brush while staying portable and easy to use as a pen.

The rich black water-based pigment ink gives strong, expressive marks for brush lettering, cards, illustration, and calligraphy-inspired writing. Once completely dry, the ink becomes water-resistant and does not smudge when used with alcohol markers or watercolour.

The rubber grip is comfortable to hold and helps prevent slipping, which matters when you are working slowly through controlled strokes or pressure-based line variation. This makes the pen approachable for beginners while still useful for artists who want responsive brush marks.

Compared with a standard felt-tip marker, this fude brush pen gives more expressive thick-to-thin variation and a more traditional brush-like feel. It may not be the best choice if you need a rigid technical line, a chisel marker edge, or a pen intended for anything other than writing or drawing.

The five nib types allow artists to choose the level of line width and brush response that suits their work. Extra Fine and Fine are useful for smaller writing and detail, while Medium, Hard Medium, and Large offer broader expressive marks for lettering and illustration.

Use the Kuretake Bimoji Fude Brush Pen for brush lettering, cards, calligraphy-style writing, illustration, expressive outlines, and decorative ink work. Vary your pressure to create thinner or thicker marks depending on the nib type.

Let the ink dry completely before layering alcohol markers or watercolour over the top. Once dry, the black water-based pigment ink is water-resistant and will not smudge with those materials.

Test the pen on your chosen paper before starting a finished piece. Smooth paper, lettering paper, sketchbook paper, and watercolour paper can each affect line sharpness, dry time, and brush feel.

Replace the cap firmly after use to help protect the nib and prevent drying. Do not leave the pen in direct sunlight or high temperatures.

Use this pen only for writing or drawing. If dropped or shaken, the ink may leak.

The hanging string is for storage, but it should not be pulled too strongly or used to swing the pen. If pulled too hard, the string may come out of the pen.

Be careful around clothing and fabric. The ink may stain and may not wash out.
