One handwritten postcard costs EUR 5. You can order as many postcards as you want, but please add them to the cart one by one. Select a country and your wish for a theme, and type a postal address individually for each card. The wishes will be fulfilled depending on the availability of postcards in each destination. We, Päivi & Santeri Kannisto, will try our best to find colourful and good-looking postage stamps. For assistance, please email or whatsapp us. Postcard mailing photos. This concept was created by the Executive Manager of Finnish Postcrossing Friends Association, Mr. Marko Kulmala.
