The Han Solo Blaster Flask is here to make sure that you not only pour your booze like a rogue, but that you’re the first shot.
The muzzle actually screws off to become your shot glass. Keep throwing them back until your friend is slumped over the table. Just remember to tip the bartender for the mess.
Unfortunately, the Han Solo Blaster Flask is just a concept by Insignificant Fish Industries. There’s no way that Lucasfilms would green-light this as actual merchandise… unless, there’s a Greedo Blaster version that gets to drink first.
