I really dunno how to see if it's original or duty free shop as i bought it from a supplier for my wedding dinner..and these are spare unused bottles.....but before purchasing you can inspect it first...it all comes with boxes...
just want to share something with u guys, if you still using the stock alarm here is a way to arm the alarm system, thks to the SWS (smart wiring system).. kinda impressive to me :P As i read, the original setting...
