You don't HAVE to make the "pew pew pew" sound every time you wear this silver and black sliding tie bar, but really you're missing an opportunity if you don't. Even better, buy a second one for a friend and have blaster battles across the boardroom table. Stormtrooper helmets recommended for your own protection. Officially licensed by Lucasfilm LTD.
