The term “Casimir” stands for openness and transparency and characterizes our mailbox series with fronts made of glass. We were the first manufacturer to use translucent materials on mailboxes. The mailboxes of the Casimir-series are part of the architecture. Their pure design does not attempt to be more important than architecture itself. The focus lies on the material which defines the character of these mailboxes. Many architects appreciate their clear and reduced design.
