Kai, a long-established blade manufacturer, has developed the plastic-free "Kami Kamitori®" paper razor. It received the highest honor, the "iF Gold Award," at the "iF DESIGN AWARD 2022," one of the world's top three design awards, and was recognized as a "product that combines excellent usability with a strong message about sustainability." It began its pre-sale on March 22, 2022, at Lawson stores nationwide.

Disposable razors have predominantly been made of plastic. Even Kai, holding the No. 1 share in Japan, used approximately 19 million tons of plastic annually. In response to customer desires to "use environmentally friendly products for daily necessities," the "paper razor" was developed.

It reduces plastic by 98% compared to conventional products, making it environmentally friendly. Furthermore, it is an ultra-lightweight model weighing just 4g. The handle is assembled from a flat sheet, and when carried, it fits into a slim package of about 5mm. Its compact appearance makes it convenient for portability.

Being single-use, it offers the appeal of always being clean and comfortable to use.

From a design perspective, it is a simple product that is accessible to everyone. The handle length is meticulously calculated to fit naturally in any hand without feeling awkward. Its neutral appearance, not limited by gender or age, suitable for use anytime, anywhere, can be called a new generation of razor.

The "paper razor®" was completed through repeated prototyping, imagining various daily scenarios of razor use. This product, which pursues and achieves both sustainability and a comfortable shave, is a testament to Kai's sincere dedication to blade craftsmanship. We encourage you to experience its comfort firsthand.
