I saw this officially licensed Space Invaders Bag while shopping with the Mrs. in Ginza. The name of the store is Idea Seventh Sense. It the first store on this list. The bag cost 20,000円 which is just under $200. It's pretty large and hard to tell if it's was meant for men, women, or both. An effeminate Japanese guy could probably get away with it, but not me.
