The postcards are slightly thinner than normal postcards what but probably because of the fact that not all inkjet printers can print on very thick cardboard. The front of the postcard is glossy, but very sticky (even before the print) what could possibly be a problem if the postcard with other letters, postcards, ... glued together. The back is printed with a field for the stamp, and address lines. The printing itself is not easy, especially one who is not very well versed in a variety of printer settings and geiegneten programs for printing. At this price you have to say, however, that you can not go wrong and the quality is also acceptable.
