History of Origami Lamp-4

Though it has been long time before Origami lamp was applied in the project, 1930 City Lodge
(http://www.1930citylodge.com/, https://www.ren-ito.com/1930-city-lodgejp.html) has accepted the use of this lamp. Until then, only some prototypes were produced, but suddenly mass-production started. With cooperation of many people and trial-and-error, they were delivered to the client.
