A new highlighter pen with a newly developed "Kitchen Guide" function that allows you to draw straight, clean lines.

It's easy to draw straight lines

The "Kitchen Guide" touches the paper surface, stabilizing the handwriting and brush width, making it easier to draw straight lines. The pen tip uses a special nylon tip and is designed to be flexible, so the entire width of the tip touches the writing surface firmly, allowing you to draw beautiful lines even on the curved inside of an open textbook or notebook. 

Handwriting is less likely to smudge

The "Kitchen Guide" touches the paper surface, preventing excessive pressure on the pen tip. As a result, lines drawn with a mechanical pencil or ballpoint pen are less likely to smudge, and ink on the pen tip is less likely to stain it.

Ink does not easily accumulate when you finish writing.

The nylon tip of the pen acts like a sponge to absorb the ink that accumulates at the end of a stroke, preventing the ink from becoming too dark and preventing ink bleed-through. 

Quick-drying pigment ink

The "quick-drying pigment ink" developed for the KIRE-NA dries in one second on copy paper (according to our research), making it less likely for the writing surface or your hands to get dirty.
