Elliot writes “Among the problems that weigh on the minds of card-game players everywhere are these: Why do some games come in those annoying double-wide packages? Why do some games come in boxes that are fragile or don’t stay closed? Is there any alternative to those stupid plastic baseball card boxes or rubber bands? What do I do if I expand my deck so that it no longer fits in the original box? What do I do if the box my cards came in distintegrates? What do I do if the cards came in a big envelope instead of a box? I come to you with the following answers: Who knows? Beats me. Yes. Make your own boxes! Make your own boxes! Make your own boxes!” Link.
