C-thru is my first lipglass by mac. It's a beautiful light caramel-beige color and I'm very happy I bought this.Yes, it' sticky but that doesn't bother me because I have to say that it's really long-lasting!I'm italian and I've always used Clinique and Pupa (it's an italian first-rate brand) but I think that I'm very hooked with mac.Next I want to buy prr, nico and lovechild but I recommend this lipglass for anybody, it's absolutely elegant and at the same time, sexy. Very J.lo
