Custom Mailer Boxes for Small Businesses

Professional branded packaging doesn't have to mean ordering thousands of boxes. Our digitally overprinted mailer boxes are designed for businesses that need flexibility, whether you're launching a new product, testing a design or preparing a limited-edition promotion.

With a square 240 x 240mm footprint and a height of just 40mm, these mailer boxes offer a practical packaging solution for appropriately sized flat products, accessories, promotional gifts and e-commerce orders.

Inside, Outside or Double-Sided Printing

Choose the printing option that works best for your packaging:

• Outside printing: Display your logo, branding or promotional message on the exterior of the box.
• Inside printing: Add a surprise message or branded artwork for customers to discover when opening their parcel.
• Inside and outside printing: Create a coordinated branded experience on both the exterior and interior.

Our full-colour digital printing process allows you to incorporate your brand colours, graphics and artwork into your packaging design. Colours may appear differently when printed directly onto brown kraft board compared with white board.

Create a Memorable Unboxing Experience

Your packaging is often the first physical interaction a customer has with your brand. Custom printed mailer boxes help turn a standard delivery into a more distinctive experience.

For an additional branded finishing touch, pair your boxes with custom printed tissue paper.
