A sealed "whistler" (Thai market) water bottle as seen in the beginning of the movie, when Richard and the French couple walk through the marijuana field.
The item is certified as screen-used by DiCaprio, although there is no actual scene where you can see a sealed bottle of that kind.
I can only guess that it had been used in a deleted scene or maybe just kept hidden in Richard's backpack or whatever.
(EXP for this water bottle is 2000)
