The brush pen is a versatile tool for the illustrator, graphic artist or the craftsman. Sakura, one of the leaders of the pen industry, offers the Koi pen. The flexible tip gives a brush style tip to this marker which allows a natural thick and thin mark.
The ink is water solvable, acid free and offers many uses. The pen can be used as is by varying the pressure to get the weight of line you need. It can also be used with a make up sponge to tint the paper by a smooth smearing or blotting. The brush also allows the application of ink to the surface of a rubber stamp, lightly breathe on the stamp and them apply to the paper while the moisture is still wet. You can also use the marker on a foam plate to make a ink wash for some specialized techniques.
The use of the marker on various papers allows a low bleed of line. It is also good about not bleeding through the paper when used directly on the surface. Colors are good and are available in singles and variety packs.
