This is a digital file download: you receive a .zip file containing two PDF files that you can take directly to your local printer. The PDF files are formatted to be printed on standard 8.5" x 11" paper (I'd recommend a card stock or heavyweight paper). Six cards per sheet (see the third image for reference).
