I had these bottles for a while and while they are the same product the glass manufacturing left them quite different. One had a bent and longer neck than the other. They also had a nice turquoise colour. While I don't often use red it is complimentary to the cyan/turquoise and the two colours played off each other nicely. A simple spot light created the relatively crisp shadows and stark highlights.
