Ear Lock Mailer Boxes

MOQ: from 1,000 pcs

Ear lock mailer boxes are corrugated shipping boxes with tab-lock or ear-lock side panels that create a secure self-locking structure for branded shipments. This format is often selected for sales kits, sample programs, product launches, and subscription shipments that need a structured hand-assembled corrugated mailer with a more defined box format than a plain transit pack.
