I found these totally original 100% Hawaiian Koa Wood postcards at a hip & funky store near Waikiki called Peggy's Picks. The Diamond Head card is just one of many postcards available.
Cards can be customized by the company who makes them, Koa Kards, or you can simply hand write your Save the Date info on the back. Either way they are a really unique way to announce your upcoming Destination Wedding.
