I've turned my drawings into postcards. This set includes three colors: simple white, rustic brown, and pale blue. The back doesn't have a postal code box, but you can use them as postcards or for interior decoration. * The white ones are slightly smaller and have "POST CARD" printed on the back. * The pale blue color in [Image 6] is the closest to the actual color. * The actual postcards have my name stamped on them individually, not printed (see Image 1). * Please note that these are handmade, so there may be some slight imperfections like smudges. Thank you for your understanding.
