Birthday Lights The design for the "Happy Birthday" card was originally created by hand using hand-cut stamps. The candle card is one of my most popular birthday cards. Now in a new design;-) There is also a postcard to send belated congratulations.... with candles that have already burned out;-) DIN A6 postcard made of high-quality 580g wood pulp cardboard, printed on both sides in 4/4 colors and approx. 1.4mm thick. The cards are printed in Germany.
