In the age of eCommerce and direct-to-consumer (DTC) brands, custom mailer boxes have become more than just a packaging solution—they’re a marketing tool, protection layer, and brand storyteller. These boxes combine structural integrity with high-impact branding, making them ideal for delivering products that need to arrive in style and safety.

Whether you're shipping cosmetics, apparel, subscription kits, electronics, or promotional items, custom mailer packaging can elevate your customer experience while protecting your goods from warehouse to doorstep.

 What Are Mailer Boxes?

Mailer boxes are sturdy, self-locking boxes usually made from corrugated cardboard, featuring foldable flaps and dust flaps that close securely without tape. They’re commonly used for shipping small-to-medium-sized products, especially in industries where presentation and protection matter equally.

They are often referred to as:

• Tuck Top Mailer Boxes
• Roll End Front Tuck (REFT) Boxes
• Custom Corrugated Mailers
• Subscription Boxes
