I have ordered new floors for my downstairs to replace my threadbare carpet and torn kitchen vinyl. Yay! Now the bad news. All ten bookcases--which are jammed--must be emptied out so the bookcases can be moved, so the floor can go beneath them. It's a lot like moving! I ordered a bunch of Banker's boxes, but they didn't seem to make a dent in our collection. A whole package of boxes later, we had only emptied one and a half bookcases. I figured I'd get down to business and get some REAL boxes. But here's the deal: a box this size may or may not stand up to a full load of books; it depends how far it's going, how well you've secured it, and whether you know anyone that can pick it up. We don't, and we can't. The box itself is well assembled, but not as heavy a quality as the extra-strength banker's box. So we are putting books in the bottom half, and tossing other, light weight items that must be moved into the top (globes, stuffed animals, wrapped dishes, etc). The good thing about these is how easily they are assembled. I'm not really mechanically gifted, but it was plain as could be, once I uncollapsed the box, that all you had to do was push straight down, and then bend the inside flap straight down to make a second, complete floor for the box. Voila. There it is. We don't need the labeling info boxes that have been provided since we aren't going anywhere, and everything is going out to the garage and then back downstairs again, but if we were moving, it would be welcome. I have moved many times, and these are a lot nicer and more uniform in size than the produce boxes I used to beg from the backs of grocery stores! When you have finished filling the box, there are two little flaps sticking out. Punch the handle spots into the sides of the box, and then bend the flaps in to make extra-secure handles. The top folds in such a way as to discourage it from falling open even if you were to leave it untaped. (However, I would still tape it shut if I were actually moving.) We also ordered some "large" boxes and heaven knows what we will put in them. They are too big for just about anything unless you have big quilts or a bunch of pillows. If I were to do it over again, I would order two packages of these, and none of the "large" boxes.
