We're moving and these were exactly what I needed for my files as I'm emptying my file cabinet to move to the new location. For the other move boxes I used your 16 x 16 x 16 inch boxes. They're great too !
This is the easiest way to get 20 boxes for my daughter’s move. Twenty seemed like a lot but we used everyone. They fold into shape quickly once you understand the sequence. They are sturdy and stackable.
