Thankfully they didn’t cost too much because I accidentally ordered the wrong dimensions. I definitely would double check dimensions before ordering. I can make use of these somehow I’m sure, but interested in buying some bigger ones, especially with the custom packing tape.

Delivere date was a few days later than expected

the order items came in two delivieries, I was a little anxious. Vista has failed all times before when I ordered from them, mostly delivering to the wrong address and even delivering wrong uniforms from another company this time they were right

Great for cards storage and shipping

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 but we do not recommend these mailers for very large or heavy items.
