Secure Shipping Meets the Ultimate Unboxing Experience

In the world of e-commerce, your packaging is the first physical touchpoint with your customer. Custom Mailer Boxes are not just shipping containers; they are a brand statement. At Customized Packaging Boxes, we engineer high-strength corrugated mailers that protect your products through the roughest courier networks while delivering a premium presentation upon arrival.

Corrugated Strength

Utilizing E-Flute or B-Flute corrugated board, our boxes offer triple-layer protection to prevent crushing, making them ideal for subscription boxes and retail shipping.

Inside & Out Printing

Maximize brand impact with double-sided printing. Surprise your customers with a vibrant design or a personalized message printed on the interior.

Secure Ear-Lock Design

Our precision die-cut "ear-lock" mechanism snaps securely into place, keeping contents safe without the need for excessive adhesive tape.

Engineered for UK Businesses

We understand the logistics of the UK market. Whether you are shipping cosmetics from London or apparel from Manchester, our mailer boxes are designed to withstand transit while keeping shipping costs low due to their lightweight construction.

  • Free design support to ensure your artwork fits perfectly.
