Mailer Boxes

Custom printed folding mailer boxes—crash-lock cartons with branded exterior print and structural QC before bulk.

Mailer Boxes

Folding cartons that ship your brand—not just your SKU

Mailer boxes are the outer frame of your unboxing moment. Tendlyn produces custom printed folding cartons with controlled board caliper, clean registration on exterior panels, and assembly that survives fulfillment handling—not flimsy trade-show samples that fail in the mail.

  • MOQ 500 Typical minimum order
  • E-flute Board options
  • Custom Length × width × height
  • 10–18d Standard lead time

The Problem

  • Generic brown cartons that look like dropship—not a branded ship experience
  • Weak tuck tabs or thin board that collapse in transit
  • Separate vendors for boxes, tissue, and stickers with mismatched colors

  • Crash-lock and tuck-end structures engineered for your product weight class
  • Structural samples and golden carton approval before bulk conversion
