|The Aperture Science Enrichment Center would like to remind you that you have failed to make good on your obligation to adopt a Companion Cube to atone for your previous act of merciless destruction. After all these years of Portal fandom, Companion Cubes are still selling strong.
Despite all subsequent instruction, take care of your Companion Cube this time. It comes in the form of a 4×4 novelty storage box, handy for the kitchen or gaming night. The weighted Companion Cube will accompany you in the home and office. You can even put cake in it, if you can manage to overcome your cynical skepticism as to its existence.
