Hello!!!  This listing is for a Space Channel 5 MINI Lunchbox!!  Box measures approx 4.5 inches x 6 inches.  From what I am able to find online, this box is from a rare promo around the time of the games launch.  Space Channel 5 is a really cool rhythm game that appeared on the Sega Dreamcast and featured a character named Ulala as she fought off aliens using her pristine dance moves!  The box is in used condition and has some minimal rust and scratches but overall is in really great condition!  This mini lunchbox would make such awesome shelf candy for any collector of the series, or gaming in general!  Thanks for looking and let me know if you have any questions!
