I bought 4 different shades when it first came out, and actually used up all 4 of them. This is a big deal or at least it should have felt that way because, you know, it does not happen to me.
Funny that I never thought I "loved" them although I knew I liked them, and using them all up did not hit me as a significant beauty event. It is funnier that I started missing them rather terribly as soon as they were gone. So I had to buy them again, this time not out of curiosity but necessity. (What?!)
