A pleasure to hold and write with – it’s a writing tool that captures the essence of Kakimori.
Pure comfort, perfection in simplicity
By paying close attention to every detail, we created a balance between modern sophistication and enduring charm. A timeless companion in your writing journey.
Semi-opaque exterior
What texture evokes the deepest connection with the writer? After much reflection to capture this moment, we arrived at the subtle look of frosted glass. Muted ink shades add the finishing touch.
Three types of interchangeable nibs
Choose from an ink-friendly roller tip and fine and medium fountain pen nibs, all made in Germany for reliable quality. Replacement tips are available to revive a clogged pen or switch from rollerball to fountain pen writing.
Extra-long grip section
The edge of the grip is a subtle but noticeable detail. The grip length has been extended to offer uninterrupted writing comfort.
Visible ink level
Ink refills are an integral part of writing with a pen. With the ink level visible through transparency, you can monitor and refill ink as needed, ensuring you never run out.
Quality Japanese manufacturing
The body and packaging are designed, manufactured, and assembled in Japan. We are committed to meticulous craftsmanship, knowing that even the smallest deviation significantly impacts writing performance.

Usage & Entretien
Daily use is recommended to prevent the nib from drying out.
When traveling by plane, we recommend filling the pen with ink after your arrival to avoid leaks during the trip.
The rollerball is recommended for use with Kakimori and Inkstand inks.
Use light writing pressure without applying excessive force on the fountain pen.

A material that retains light
Frost was born from a question that Kakimori, the stationery shop in Kuramae, Tokyo, has long asked itself: which material makes you want to pick up a pen every day? The answer lies in a semi-opaque exterior, wrapped in translucency, allowing light to pass through without revealing everything. The range is available in ballpoint and fountain pens, with a fine or medium nib, and in four shades: translucent, green, purple, and amber. A pen designed for daily writing, pleasant to hold and to look at.





FROST, BY KAKIMORI
What sets these pens apart
A semi-opaque exterior
The body is molded from a translucent material that hints at the interior without revealing it. It is this veil of light that gives the series its name.
Ball or feather, same silhouette
The range is available in ballpoint pen and fountain pen, with a fine or medium nib depending on the desired line. The motion changes, the shape remains the same.
Four shades
Translucent, green, purple, and amber. One shape and four ways to read the same material, depending on the room’s light.
The tip is replaceable
The nib and refill are made by Schmidt and can be easily changed when the tip clogs or when you want to switch to a different type of line.
A sought-after balance
Kakimori worked extensively on every detail, the shape, the material, the balance in hand, before finalizing the design of the series.
Designed for everyday use
Frost is not a collectible item. It is made to be used every day and to bring calm to ordinary moments.
