Being a true geek isn’t about what everybody can see, it’s about what you are underneath, or what you wear underneath, and what better way to share your love for Portal than with a pair of companion cube panties. You’ll always have your companion cube with you wearing these but we can’t guarantee that your boyfriend won’t try to open the cube.
These underwear look like a companion cube, which is designed to be the object of your affection while spending time at the Testing facility. You see where this is going, buy them for the non-cubic, human-shaped object of your affection today! (Note: It is perfectly acceptable to be the object of one’s own affection.)
