This is a short video of a woman showing how to reconstruct a cardboard box that's slightly too short for an object you're trying to fit in it. Alternatively, smash it in there like a normal person who knows the delivery company is just gonna beat your shit up anyways. Or, if you're like me, decide, screw it, this looks way too complicated and, dammit, I bought this crap on Amazon when I was drunk, and I'm drunk again now and I'm keeping it.
Keep going for the video, which makes a lot more, but still not much, sense.
Thanks to Jeffrey S, who agrees magic is everywhere, you just have to look for the wand.
