Lighter weight but equally effective for purpose. Supports when stacked. Assembly same method but this one can go askew if not creased/aligned properly. If you are OCD get the heavier ones cost only a little more; or tape bottom / corners
The cartons are easily assembled and quite strong. I've loaded them with heavy books and housewares and never felt they weren't up to handling the job.
It's been about 25 years since I put one of these together so I paid strict attention to the directions. All went smoothly even at my 90 years of age! I'd buy them again if needed … or if I live that long! :~)
