[KAYOU+] Limited Edition "AIMVISION Edition_001 KOHAKU" to Commemorate First Anniversary of Brand Launch

KAYOU Co., Ltd. (Headquarters: Minato-ku, Tokyo / President and CEO: Li Qibin) will launch "AIMVISION Edition_001 KOHAKU" on July 25, 2026 (Sat.) to commemorate the first anniversary of the brand "KAYOU+."

"AIMVISION Edition_001 KOHAKU" is a limited collection of 3,000 sets, inspired by the year KAYOU+ has been in operation.

It includes items planned and developed exclusively for this product, centered around a limited-edition drafting mechanical pencil.

The Meaning Behind "Edition_001"

"Edition_001" is not just a product number.

It is the name given to record the stories and craftsmanship born at the brand's milestones as a single collection.

This collection, commemorating the brand's first anniversary, is titled "Edition_001" as its first record.

Theme: "Amber"

"Amber," formed over long periods, embodies time itself.

In its colors shifting from dark brown to red and then to gold, we have entrusted our aspirations for the brand's past year's journey and its future path.

This collection expresses the world of "Edition_001" as a whole, featuring the "AIMVISION PRO" in a limited amber-inspired color and an A5 notebook, along with a special pen case planned and developed for this product.

Five Original Products to Design the Time of "Writing"

"Edition_001" is not merely a limited set.

It was planned as a collection to enrich the very act of "writing" at the milestone of the brand's first anniversary.

Centered around the main product, the mechanical pencil "AIMVISION PRO -KOHAKU-," it covers everything from preparation before writing, the time spent writing, to after finishing. All items in this collection have been newly planned and developed to design the entire process related to writing.

AIMVISION PRO Limited Edition -KOHAKU-

A limited color for AIMVISION PRO, commemorating the brand's first anniversary.

Utilizing the natural base color of brass, a gradient color inspired by "amber" has been adopted.

All 3,000 units are engraved with serial numbers.

Each piece has a unique painted finish, making it a one-of-a-kind special item.

Dedicated Pen Case

A dedicated cowhide pen case designed for the AIMVISION PRO.

Its three-dimensional molding is designed to beautifully hold and retrieve writing instruments, encompassing the entire action.

This product enriches the time spent with the AIMVISION PRO, from the moment you pick it up to the moment you put it away.

Ruler Letter Opener

An original product newly developed for this item, integrating a ruler and a letter opener.

Its thickness and grip have been carefully designed to create an object that naturally invites you to pick it up on your desk.

It is a special item exclusive to Edition_001, combining functionality and beauty.

Eraser Case

A dedicated eraser case designed exclusively for this product.

It features a mechanism that finely adjusts and secures the length of the eraser, designed for comfortable use until the very end.

Its design echoes the AIMVISION PRO, expressing the collection's worldview down to the finest details.

A5 Notebook

An original notebook developed for this product.

With the theme of "a writing feel as if you can hear the paper breathe," it deliberately pursues a writing sensation that allows you to feel the presence of the paper, rather than the smooth writing feel that has become mainstream in recent years.

For the text paper, "Dandereido CoC," a Japanese paper that offers moderate resistance with minimal bleeding or show-through, has been adopted. We have also paid close attention to material selection, choosing CoC certified paper made from appropriately managed forest resources.

The notebook cover features a deep amber color, aiming for a design that deepens in affection with use.

Furthermore, details such as a 5mm grid and 2.5mm auxiliary lines, the brand's symbolic "+" guide, and thread binding have been incorporated to enhance the comfort of writing time.

The collection box is designed with the concept of "a record of the brand's time bound into a book."

Its appearance reminiscent of a Western book and its sturdy corner fittings are inspired by tomes that gain value with age.

It is not just a box to hold writing instruments, but a volume to beautifully preserve the time of "writing."

This is a limited-edition collection box that symbolizes the world of "Edition_001."

Specifications to Enjoy the Charm of Brass for Longer

For the drafting mechanical pencil "AIMVISION PRO" released in 2025, we received feedback from customers who wanted to "enjoy the natural texture of brass."

In response to this desire, this product features a limited color that utilizes the base color of brass.

By combining a gradient coating reminiscent of amber with a clear coating that suppresses discoloration, the beautiful texture unique to brass can be enjoyed for a longer period. Another characteristic is that the delicate painting process creates a unique expression for each item.

All 3,000 units are engraved with serial numbers, adding to the specialness of the collection.
