It is a bookcase/container which alternates doors and open shelving units. To give birth to this project was the idea to alternate closed and open elements, which can show and contain at the same time. The apparently casual alternation creates an original optical effect which recall to your mind the vertical lines and white spaces of the bar code and from here raised the idea of the name. The structure is mat lacquered in our colours, while the doors can be mat, glossy or black walnut and wengé.
