Roll End Tuck Top (RETT) Box Explained: Uses & Benefits

rett box with dieline

Roll End Tuck Top (RETT) boxes are one of the most widely used corrugated mailer styles for ecommerce, retail, and subscription packaging. Known for their clean unboxing experience, structural strength, and versatility, RETT boxes are designed with a front tuck closure that securely locks the lid into place.

Most packaging failures in ecommerce don’t occur during transit—they occur during handling and unboxing.
RETT boxes help address this by combining secure closure, durability, and user-friendly access in a single structure.

What Is a Roll End Tuck Top (RETT) Box?

A Roll End Tuck Top (RETT) box is a self-locking corrugated mailer that features:

  • Roll-over side panels for strength
  • A tuck-in front closure
  • No need for tape or external sealing (in many cases)

This structure creates a rigid, protective enclosure while maintaining a premium unboxing experience.

Where to Purchase RETT Boxes

Not all suppliers offer both stock and custom RETT boxes.

Key considerations:

  • Stock sizes are limited to standard dimensions
  • Custom RETT boxes allow:
    • optimized sizing
    • improved product fit
    • better cost efficiency

👉 Custom sizing often reduces material waste, shipping costs, and product damage.
