Thanks Red that's very helpful
Interestingly I found this on one of the TT threads
2nd pic she seems to be also the gel Res2....
Hmmm so I guess I can safely assume the Res4 would be slightly more matt looking than the Res2
Appreciate those who had helped here. Becos I'm not located in the US so buying this exclusive color will not only cost me more but also more effort too. So just gotta be sure on the safe side
