Mailers vs Shippers - What’s the Difference?
When you’re looking for the very best in presentation plus function, a mailer box is your go-to solution. Mailers are one-piece boxes that easily assemble without tape or glue. They are ideal for retail display or gifting and are sturdy enough for shipping. They are the favorite box style for ecommerce and subscription boxes.
Shipping boxes are also one-piece boxes, but require packing tape for top and bottom closure. They are designed to take the punishment of heavy-duty shipping and warehousing while maintaining a brand presence. A custom-printed shipper is a powerful brand ambassador throughout its journey.
