Whenever I have to move family or help someone downsize I always recommend these boxes. They are sturdy and make moving heavy books and collections of small items more manageable. When you’re finished with them repurpose them for storage. Or flatten them and store under a bed or sofa.
I'm re-boxing all the holiday and keepsake stuff on my basement shelves. The first 12 boxes look so good I re-ordered another 12 to have everything look as good as the first ones do.
