Your cart is empty.3 x 3 x 18" Kraft Square Mailing Tubes. Square tubes will not roll around which makes them easier to pack and ship than traditional round mailing tubes. These one piece tubes ship flat to save space. Tubes fold together fast without tape or glue. Constructed from 200#/ECT-32-B kraft corrugated. Proudly made in the USA!

I was worried about whether the boxes and contents would survive shipping. My contents were neither heavy nor unbalanced. So that may have helped. But shipments to NYC and Minneapolis alike arrived in good condition as well as closer destinations. No complaints at all.

From the images I thought they could stand on their own while you place the item in from the top. The sides don’t hold up without the top side tucked in. Cardboard is also too thin.

Realized not what needed too late to cancel the order. Return was smooth. Look like good quality.

These work great and are reasonably priced but the quality matches the price. Hard to get the tabs for the flaps into the slots, etc. They do the job for shipping a poster and are well priced but if you are going to ship grandma's priceless china pick a sturdier box.

I bought these hoping Amazon's picture was incorrect. These are not tubes. Tubes are cylindrical , round or oval. Update your description. These are long boxes.

Used for shipping. I have purchased other 200# shipping tubes like this that are much stronger. Not pleased
