Partners Brand Deluxe Literature Mailers 14x10x4

These white mailers measure 14 by 10 by 4 inches and arrive in a pack of fifty. They suit offices, warehouses and e-commerce sellers who need rigid protection for catalogues, brochures or documents during transit. The carton construction resists crushing better than standard envelopes.

Sustained shipping performance

Under repeated handling the sidewalls keep their shape and the self-sealing closure stays shut without tape. Contents remain flat even when the package sits at the bottom of a stacked pallet for days. The white exterior accepts handwritten addresses or printed labels cleanly.

Quick setup and common issues

Each mailer folds into shape in seconds and the peel-and-seal strip closes with one press. The main mistake is overstuffing beyond the four-inch depth, which can split the glued corners. Store the flat pack in a dry area to prevent the adhesive from losing tack.
