Indeed, I was selling the Sega Saturn Virtual On Twin Stick box & packaging (actually, "sold", not "was selling"). :]
But, the sticks themselves are readily available on eBay at reasonable prices, & they're a nice setup, so why not just buy the Saturn or Dreamcast Virtual On sticks & use them? Is this for a cabinet? If so, pull them from their enclosure & add them to your cabinet's control panel "base."
