Custom PR boxes for launches, media kits, and brand presentation.
Plan an ear-lock corrugated PR box around the products, message, and opening sequence. UPG manufactures custom PR boxes for brands worldwide with exterior and interior print, custom inserts, and selected finish options.

What buyers should know first.
A custom PR box is a branded ear-lock corrugated mailer planned for product launches, press outreach, media kits, gifting, or event presentation. The box can combine exterior and interior print with a custom insert after the product arrangement and dimensions are reviewed.
Where pr boxes fit best.
Start with the campaign or program goal, then develop the mailer around the products, presentation, quantity, and destination.
Product launches and press outreach
Media kits and editorial presentations
Branded gifting and event kits
Multi-product launch collections
Shape the brief before the artwork.
A clear product and presentation plan helps the structure, insert, and artwork move in the same direction.
Build around the launch story
Plan the outside, inside, and product reveal as one presentation rather than treating each surface separately.
Confirm the product arrangement
Share the number of products, their dimensions, and the intended layout before the insert and mailer structure are finalized.
Prepare one clear brief
Include the launch date, quantity, delivery country, visual references, and any existing artwork or dieline information.
Coordinate the box, print, and product arrangement.
These options are reviewed against the approved ear-lock structure, project quantity, and presentation goal.
What to send for a useful first review.
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.
