 <p><b>thick blank cards with postcard pre-printed</b></p> <p>50 postcards<br> 10.5 x 14.8 cm (DIN A6)<br> Offset printing 0/1 (black: rectangle for postage stamp, 4 lines for the address, 1 line to delimit the text field)<br> Chromosulfate cardboard, matt coated on both sides, 450 g/sqm</p> <p>Unlike our other postcards, the surface is painted matt.   So it is not a natural cardboard with an open surface.   This means that you can easily paint and write on the box with waterproof pens (such as Edding or most felt-tip pens).   Thanks to the 450 g/sqm it is quite thick and stiff. <br> Please note: hardly any printer can print on 450 gsm cardboard.</p>
