Well, great news! I just made a limited run of postcards on heavy cardstock - similar to my Kimono girls set- and will be giving you early access!
Each set contains all 5 5x7" cards for $30, including shipping. They're printed on extra thick, premium 600 gsm stock with black seams. They can literally stand up on their own! :D
It's a limited run of 10 sets total. If interested in a set, message me!
