What Are Custom Printed Mailer Boxes?
Custom printed mailer boxes are sturdy corrugated or card boxes designed for shipping, branded with your logo, messaging, or full artwork. Featuring secure tuck-in flaps or locking tabs, they keep contents safe in transit while delivering a memorable unboxing experience. Unlike plain boxes, these are fully customisable on both the inside and outside.
They’re widely used in ecommerce and retail environments where branding, presentation, and protection all matter.

- Subscription services (beauty, health, food, books)
- Ecommerce product shipping
