RETT (Roll-End Tuck Top) vs Indestructo Mailers

Roll End Tuck Top (RETT) mailers and Indestructo mailers are both designed to ship products securely, but they differ in construction, strength, and ideal use.

A RETT mailer (Roll End Tuck Top) features a one-piece design with a hinged lid and side panels that roll inward and tuck to create double-layer side walls. This construction provides good stacking strength and a clean presentation, making RETT mailers a popular choice for subscription boxes, e-commerce shipments, kits, literature, and lightweight to moderately heavy items. They assemble quickly without tape and offer a professional, retail-ready appearance.

An Indestructo mailer is built specifically for heavier or more fragile contents that require extra protection. It features multiple overlapping layers of corrugated board on the sides and ends, creating reinforced edges that resist crushing, punctures, and rough handling during transit. Because of this added rigidity, Indestructo mailers are commonly used for shipping books, catalogs, manuals, framed prints, and other flat items that need maximum edge protection.

RETT: strong + polished presentation

Indestructo: heavy-duty protection
