KATAMAKU

KATAMAKU is a collection of products that utilizes the unused parts of the membrane material that were used to build tents and stadiums such as the Tokyo Dome. Because the leftover materials are rarely utilizable for other purposes, they are usually discarded in large quantities. With KATAMAKU, the materials that were to be disposed of were made into various cases and bags for everyday use with excellent durability.

Beautiful, Durable Stationery Collection Made from the Same Membrane Material of Tokyo Dome

KATAMAKU is an eco-friendly series of products that utilizes unused parts of the membrane material that were to be thrown away. They were made into various cases and bags for everyday use. The products use industrial membrane fabric, such as the material that's used to build the roof of Tokyo Dome.

How KATAMAKU Was Made

Katamaku can be assembled with ease, and in order to take advantage of the beauty of the material, we have designed each product as one piece of folded cloth, like a kimono.

About the Materials

■ Fluororesin Coated Fiberglass
KATAMKU is made from the same material used for the roof of the dome and stadium, such as the Tokyo Dome. It has firm tension, it is strong against dirt, and turns white when it hits sunlight. It is due to such characteristics that the dome tent stays pure white even if it is outdoors for a long time.
In KATAMAKU we use it to manufacture products such as card case, document folder, and pen case.
■ "PVC-Coated Polyester Fiber Fabric"
It is a material mainly used as a fabric for tents and warehouses. Light can go through the material regardless of its high-intensity, and it is soft and feels very good. There’s a wide variety of colors to choose from. We designed them into book covers and pochettes (clutch bags) for your daily use.

These materials are very durable even though it is often used as construction materials, so they are excellent in durability, water resistance and heat resistance. Let's take a look at these products that blend into our lives, with the utilization of materials that were to be thrown away.
