Help me identify this flask

I was watching the movie Brick (2005), and at 1:06:48 I noticed a flask that is identical to one I found in a thrift shop and bought for $10.

I really already loved the flask, it has an amazing pattern and people always ask about it (so much for being discrete). But now I just show it off at parties.

I'd love to find out if I can get another one somewhere, or atleast more information about it.
