One of the more versatile expanding direct mail pieces, the exploding map is available in a wide variety of sizes from business card to size to A4, or larger. If you have a large amount of information to get across then instead of making the exploding map larger you can have a 6pp or 8pp cover. If you want to add a bit more to your mailer design then you can die-cut the cover. The exploding map mails out flat. Once opened, this promotional mailer expands and reveals an inner panel almost 4 x the size of the cover, revealing a large printable area to convey your messages or promotional map. After reading, the exploding map can be stored flat and referred to. This is a popular direct mail piece for an exhibition give away.
