Koichi Suzuno and Shinya Kamuro from Torafu Architects designed the 'Clopen' shelf, manufactured by Tanseisha. When pulled, a secret drawer appears, to store your valuables such as jewelry, stamps and passbooks.
The shelf panel is constructed from elaborate aluminum parts, and at 34mm thick, it looks as if it's made of natural wood.
Attaching sliced veneer to a thin structure, they made space between two boards which can be opened using magnetic keys.
The impression of the shelf completely changes when its hidden aluminum space is revealed from within the sliced veneer surface.
