I’m with @JonnyH . The BCW or similar are the way to go. I used them last time and still have them now for storage. The uhaul ones weren’t as easy to carry and some ripped. Good thing about uhaul though is I think you can return ones you don’t use and they are a lot cheaper
In my experience the bcw type boxes are a waste of money, they are single walled and don’t hold up. The uhaul HEAVY DUTY small boxes are double walled and the handles will hold up. I had 46 of these when I moved and not one suffered any damage.
