Storage boxes are great for storing your stuff when you move or have to use storage. However when all the hard work of unpacking is done the fun can begin.
You will no doubt have lots of storage boxes and I would recommend that you sell your secondhand boxes to a storage facility, however keep a few for the kids to make cubby houses and other fun stuff.
However if you don’t have kids or your babies are your 4 legged friends, think outside the box and build a storage box cat condo. They will love you even more.
