This creative direct mail idea is a pop up rectangle affixed to a 4pp outer. This bespoke project demonstrates that you can add a booklet with extra information about your product to your pop up mailer. The 4pp booklet ( with 2 pages, 4 sides in total for content) can carry product information, while the cube brings an element of fun and interaction to the campaign. This direct mail piece can be supplied in a board or paper envelope.
