Pigeon is all about connection. It's about one-to-one messages to friends and family that have a real emotional depth and meaning (even if it's just to say hi!). And it's about rediscovering the joy of pen on (beautifully illustrated) paper. Pigeon Posted plants up to 30 trees a year via a regular donation to the John Muir Trust in Scotland. 6 different coordinating designs/colors in each pack.
