I recently moved with these boxes. The delivery was made by Hermes, which is the delivery time a bit prolonged, but it was still acceptable. When you first look at the boxes, I noticed that the cardboard was a little thinner than my other boxes and they were also a little smaller. When assembled, they were very stable. There are certainly more stable versions that can carry larger loads, but if you so unpacked the boxes, that they can still raise himself well, then you can not go with the boxes absolutely wrong. I just annoyed that I did not order 20 boxes :-)
