Very sturdy. Put together in seconds.

So easy to assemble. Perfect size to organize my office and they stack very well.

These boxes are VERY sturdy!

These boxes are good. The big plus SUPER easy to set up. Bargain price.

Like the increased strength. I have the lighter weight & the heavy duty are better.

Very sturdy boxes

Nice quality

very sturdy

Seems weird to sing the praise of a cardboard box but there probably isn't a person reading this that hasn't been grateful for having these sturdy boxes with handles during a move. The old ones were like puzzles you had to punch out and fold and twist to form the box and the lids never worked for me. Now these, are ready to "push" together to form one of the most sturdy boxes you'll need for the heaviest of boxable items. Oh, yes, you can use them as a file box but I've never used them for that. No, these are a movers most valuable asset and they can reused over and over. The lids are not attached to the main box and are precut and ready to fold as well. Great product that got better. shipping was fast (I love to treat them to my moving friends and family)

The best box for storage and ease of moving! The size and design makes it very manageable to retrieve and move.
