A clear product and presentation plan helps the structure, insert, and artwork move in the same direction.
Plan the outside, inside, and product reveal as one presentation rather than treating each surface separately.
Share the number of products, their dimensions, and the intended layout before the insert and mailer structure are finalized.
Include the launch date, quantity, delivery country, visual references, and any existing artwork or dieline information.
These options are reviewed against the approved ear-lock structure, project quantity, and presentation goal.
You do not need a finished specification to start. Share the facts and files already available, and UPG will review the next structural and commercial steps.
