This unique object is the Revolution pen from Parafernalia. The pen, which is hand-made with 31 miniaturized metal components and a push mechanism, has been exhibited at the Modern Art Museum in New York. The pen has been available as a ballpoint or a mechanical pencil for a while but can now also be purchased in a fountain pen model for $90. It may look odd but the triangular shape is actually said to be quite comfortable to write with.
