I needed some sample boxes for a toy drive we are conducting. We wanted to make sure we got the right size and shape. All the sample boxes I ordered came at a good time, and I was able to find the right size for us!
The boxes are very sturdy

Glad I had the opportunity to purchase several sample boxes before committing and investing in a box size that did not meet my business needs. I ordered 3 and found 2 sizes that could work. This was helpful!

i didn't think it'd be as thick as it was, but the cardboard is really sturdy. can definitely be tossed around a room and survive the barrage.

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
