A great box. Wish it would’ve been blank so I could reuse it. But nice to see.

This little mailer box is easy to put together and sturdy. It wasn't the perfect size for what I need, but I will be adjusting the size.

Really happy with the samples and plan on ordering several of the smaller box. It was much larger than I had anticipated.

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
