Sega has unveiled the perfect companion to its Genesis and Saturn Zippo lighters -- the Yakuza 4 hip flask! Perfect for covertly storing your favorite Japanese whiskey (I recommend Nikka Yoichi), this flask comes with the Yakuza 4 special edition available on Sega's web site. According to Andriasang, "The 170ml, 211g flask is made of stainless steel and sports a laser imprint of hero Kazuma Kiryu's dragon tattoo."
