Moonphases! Perfect for Postcard enthusiast and Postcrossers! 

Each postcard is approx. 4"x6". Printed on hand-cut 300gsm glossy cardstock. These will include the "HVPC Postcard section" on the upper left where you can include things such as Postcrossing ID, Date, weather, and song or what you're currently listening to. Each section isn't necessarily labeled so you may add a combination of things to each box.
