Before placing an order for custom boxes, we ordered all the different sizes of the mailer box samples and the quality of all of them made us finalize our custom box order. Highly recommend giving these samples a try first to see if it will meet your needs.

E-flute is very thin (1/16") corrugated cardboard. It’s very easy to fold and is excellent for printing. Sturdy and crush resistant, it’s a good option for shipments – we do not recommend these mailers for very large or heavy items
