Our custom printed mailer boxes are made from a sturdy 1.5 mm white or brown E-flute cardboard, so you can skip outer boxes and save on shipping costs. And with 2-sided printing, you can even add a special message or design to the inside of your postal boxes. We also offer mailer boxes in different sizes to suit a range of needs. Plus, they’re recyclable and are pre-creased for your convenience.

Frequently Asked Questions

Our custom mailing boxes are perfect for delivering your products or promotional items to your customers. The 1.5mm E-Flute cardboard material is durable enough to be sent on its own – so you won’t need an outer box to protect your package. Plus, the exterior printing ensures that your branding is front and centre.

E-Flute is very thin (1.5 mm) corrugated cardboard. It’s easy to fold and is excellent for printing. It’s a good option for shipments because of its sturdiness. However, we don’t recommend using our mailing boxes for excessively large or heavy items.

This depends on your order and the delivery speed that you choose.

For a full breakdown of our shipping options and costs, you can visit our  delivery page. We’ll always show you any delivery charges in your cart at checkout.
