I am so pleased with the quality of the boxes. Very sturdy and the print colours have come up great. I will definitely order again for another project. They received so many compliments. Thank you!

Love these so much I'm about to order again all my business products come from use and such a quick turn around

Sad and waiting on another replacement

I’m in my second replacement due to my boxes have odd white marks in the print. It’s like there is no human checking the quality before they are dispatched. The boxes, once folded into shape don’t connect tightly into shape either. It’s not very professional for a business look for my packing. The replacements have been speedy, but it’s too unreliable for me to use this company again.

Response from Vistaprint Customer Care Team:

Thank you for your feedback, we’re really sorry to hear about your experience, especially having to go through multiple replacements due to the same issue. We understand how frustrating this must be, particularly when the product is intended for professional use. The concerns you’ve raised about the white marks in the print and the box structure not fitting securely are definitely not the standard we aim to deliver. We appreciate you acknowledging the speed of the replacements, but we also recognize that reliability is just as important. Your feedback will be shared with the relevant team for review.

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.

Not at this time, because brown E-flute cardboard has a natural brown tone that could make white elements look muted or subdued.

If you want to use white elements in your design, we recommend choosing the white E-flute option.

The first box from your order will include a QR code for logistics purposes. But don’t worry, the QR code is printed on an inner flap that folds into the box, so it won’t show when you assemble your box.
