This reusable leather mailing envelope, permanently embossed with two addresses, is designed to be sent back and forth between the same two people–carrying a message one way, just to be turned other-flap-out and carry the response back.

The envelope and its stationery cards were designed in 2011 and manufactured in 2012 for exhibition at the School of the Art Institute of Chicago’s 2012 BFA Exhibition, and forms a suite of stationery products with Scroll and Pen.
