À propos de TOYO STEEL
Toyo Steel Co. Ltd, founded in 1969 in Osaka, is the specialist behind the renowned Toolbox known for its many qualities: lightweight, portable, and extremely durable as it is made from a single seamless piece. Every detail is well thought out: rounded edges to prevent injury, retractable handle, locking clasp, embossed top/bottom for stacking. The use of the toolbox is versatile; it fits perfectly in every room of the house to store pencils, sewing threads, phones, glasses, kitchen utensils... and of course, tools.

Born in Osaka, adopted indoors
Since 1969, each Toyo Steel box has been pressed from a single sheet of steel in Higashi Osaka. Designed for the workshop, it has gradually moved from the workbench to the home. On a desk, a shelf, or a dresser, it stores stationery, plants, or keepsakes, and its design has remained unchanged for over fifty years.





TOYO STEEL EXPERTISE
What makes these objects unique
A single sheet of steel, zero welding
Each box is made from a single sheet of cold-pressed steel. No welding, no weak points: a monobloc structure built to last for decades.
Rounded corners, no sharp edges
Rounded corners are not just aesthetic: they eliminate sharp edges, make cleaning easier, and enhance the structural strength of each box.
Lightweight but indestructible
Cold-rolled steel offers an excellent strength-to-weight ratio. Easy to carry, hard to damage. An object designed for everyday use, not for the closet.
Stackable, modular, alignable
Designed to live side by side. The dimensions follow one after another by module, the lids stack flat, and each box finds its place on a shelf or countertop.
Epoxy finish, durable color
Epoxy paint resists scratches, rust, and stains. The colors retain their brightness over the years, even with heavy use.
Made in Japan since 1969
Each box comes from the same workshop in Osaka. More than half a century of expertise, a design that has hardly changed. Because it didn’t need to.
