Strathmore Mixed Media Postcards come ready to customize and are suited for a variety of wet and dry media, including watercolor, gouache, graphite, pen-and-ink, colored pencil, marker, collage, and more. The front of each card is blank, with the reverse side pre-printed with the standard markings of a postcard, making it easy to mail and share your artwork.

Each tape-bound pad contains 15 heavyweight 184 lb (300 gsm) cards. Strathmore's mixed media paper is acid-free and offers the attributes of watercolor paper but with a vellum finish suitable for drawing.
 
Cards measure 4" x 6".
