This is the flask you're looking for -- to get turnt up.
If you ever find yourself drinking in a cantina in Mos Eisley, Etsy seller Insignificant Fish Industries has the perfect flask for you that is modeled after Han Solo's DL 44 blaster.
The 4.4-ounce "First Shot" flask utilizes the blaster's silver muzzle to conveniently unscrew to become a 1.5 ounce shot glass, so you don't have to take any awkward sips.
At the moment, the blaster flask is just a concept, since it might not be legal to actually create this kind of merchandise without Disney or Lucasfilm's permission. But a Jedi can dream.
Han would have definitely been into this boozy sidearm if it existed in a galaxy far, far away. Of course, if he did, only Chewie would be able to understand his constantly slurred speech.
