Black File

Material | Polarizer / Polypropylene
Country Of Origin | Japan

A mysterious plastic file folder looks transparent at one time and opaque on the other time. If you put documents in this folder and rotate the polarizing plate on the surface by 90-degree, inner texts are suddenly hidden as if melt in the darkness. Polarizing plates transmit or shut the light when overlapped. By utilizing this phenomenon you can protect precious information in rotating the square plate. If you put it into the attached envelop and submit to the client, it is just like a confidant who shares clandestine information. This folder stores your clear information a bit darkly.
