Are you one to call yourself  a retro gaming geek? Then these Space Invaders Business Card Holders should suit your office wardrobe nicely, or would be a suitable accessory the next time you head over to a geek convention.

Available in two designs, Black and Red, these official Banpresto merchandise will set you back at USD 10.90 each (with free international shipping to certain countries). Personally I like the Space Invaders motif on the Red case, but the Black one rocks as well with the arcade screen printed on it.
