The Flapper has been a favorite among advertisers for years – four selling panels that turn in succession to tell your marketing story in an interactive, engaging, and almost addictive way. This affordable, extremely versatile design can be used as a self-mailer, a magazine insert or a premium. And can include inkjet imaging, scents, scratch-offs, bar codes and bonus compartments. One warning: once you start the Flapper, you may not be able to stop.
