The briefcase from TOYO STEEL

Konstella is a new brand of elegant briefcases designed by the Japanese steel company Toyo Steel. Based in Osaka, this company specializes in lightweight steel utility products such as toolboxes and casters. It is therefore surprising that something as elegant comes from a company whose core business is the manufacture of lightweight steel utility objects. But Toyo Steel is used to using its flawless ingenuity to merge the worlds of style and utility. 

The founder of Toyo Steel, Keiyu Hisashi, had an eye for design. He was the one who created the Trusco Deluxe toolbox in 1947. The design has remained largely unchanged and its blue enamel finish is immediately recognizable. It has been awarded the Good Design Awards in Japan as well as by the Museum of Modern Art.

Although the original founder passed away in 2014, his spirit is still present in the company. In 2016, the company partnered with the product development studio Iroyori to create Konstella. Inspired by the constellations of the sky, the team set out to design a carrying case allowing the modern and nomadic professional to transform any space into a desk. By sourcing leather from Ehime Prefecture, which has a millennial history of leather product manufacturing, and combining it with its own pressing method, the company created its Konstella briefcase line.
