Plain Mailer Boxes are unbranded, die-cut corrugated shipping boxes for sellers who want clean, no-print packaging that ships flat and folds in seconds. We manufacture them in the US from sturdy corrugated board and can add custom printing whenever you are ready to brand.
A blank box keeps your unit cost low while still protecting product in transit. The one-piece, tape-free design folds into a snug enclosure with interlocking flaps, so your packing line moves faster and your items arrive without rattle. Subscription sellers and resellers often use plain mailers as a neutral base, then add a branded sticker or sleeve later.
