Kuretake ZIG Cartoonist Ai Liner Ultra Fine Brush Pen

The Kuretake ZIG Cartoonist Ai Liner Ultra Fine Brush Pen is designed for artists who need a very controlled black brush line. Its ultra-fine brush tip is similar to the fine tip style found in eyeliner cosmetics, but this product is a writing and drawing instrument only.

The Ai Liner was made possible through Kuretake’s experience manufacturing inks, pens, brushes, and cosmetics. That background gives the pen an elastic, responsive brush tip that can handle delicate expressions in illustration and hand lettering.

For manga and comic work, the ultra-fine tip is useful for hair strands, eyelashes, facial details, texture marks, fine contours, and expressive line variation. It gives a more fluid feel than a rigid fineliner while still staying precise enough for small details.

Once the pen line is completely dry, the ink will not bleed when used with alcohol-based markers or watercolour. This makes it useful for artists who like to ink first and then add colour with markers or water-based painting techniques.

Compared with a standard brush pen, this liner is better for ultra-fine detail and delicate control rather than bold lettering, heavy fills, or large black areas. It may not be the best choice if you want a broad brush marker, a chisel tip, or a rigid technical pen feel.

Use the Kuretake ZIG Cartoonist Ai Liner for manga linework, delicate ink drawing, fine illustration details, hand lettering, and controlled expressive marks. The elastic ultra-fine brush tip responds to pressure, so lighter pressure creates finer marks while slightly more pressure gives a fuller brush line.

Let the black ink dry completely before layering alcohol-based markers or watercolour over the linework. This helps prevent bleeding and keeps the drawing cleaner when adding colour.

Test the pen on your chosen paper before starting a finished piece. Smooth illustration paper, manga paper, marker paper, and watercolour paper may each affect how the brush tip feels and how quickly the ink dries.

Replace the cap firmly after use to help protect the brush tip and ink flow. Do not leave the pen in direct sunlight or high temperatures.

This product is a writing instrument, not a cosmetic tool. Do not use it on skin, and do not use it for anything except writing or drawing.
