Toyo Steel ST-350 Two-Level Cantilever Toolbox

The classic Japanese steel toolbox that went from workshop to design icon: Toyo Steel’s ST-350, with a cantilever lid, adjustable tray and 16 colors.

Toyo Steel designed the ST-350 for workshops and garages, and it has become one of the most recognizable storage boxes in design-led homes. Open the lid and it unfolds on a cantilever, lifting a tray with adjustable, removable dividers above a deep lower compartment, so everything is in view at once. The steel body measures L 13.8 × W 6.9 × H 8.7 in and weighs 2.6 kg (5.7 lb), and a hole lets you add a padlock. Use it for tools, art supplies, make-up, medicine, snacks or tea. Because it was made for industry, it is painted rather than powder coated and has no clear topcoat: small imperfections can fall within Toyo’s tolerances, and chips and wear with use become a patina.

Why we carry it

We’ve been curating design-led pieces since 2009, and Japanese craft objects like this one earn their place by being used every day. Toyo Steel has made steel toolboxes in Japan since 1969. Its boxes were designed for workshops, garages and factories, but their clean lines and colors have made them design classics at home, where they hold art supplies, make-up, medicine, snacks or tea as easily as tools.

Buy once: durability and care

Wipe with a soft, dry or slightly damp cloth. The paint has no clear topcoat, as the boxes were made for workshops, so small chips, scratches and signs of wear can appear with regular use; they become part of its patina.
