There was a vendor out front of the outlet mall that was selling mystery boxes for 300 Yen each. Each box was completely wrapped and contained a prize of some sort. He said some had video games and figures in them. I just couldn't help myself; I bought a mystery box. My box contained a box of 80 plastic zip lock bags featuring these "Pretty Cure" characters. Since the bags are really tiny, I can't think of what you'd use them for besides adding a little splash of Japanese culture to your drug dealings.
