Vial Trials are my reviews of sample fragrances given out by sales people from various store purchases. Compared to my posts about full bottles--which are mostly positive because I already like them in the first place, that's why I bought them--Vial Trials are hopefully less one-sided since they were just given to me; I didn't pick them. This sample, Tempo EDP by Diptyque , has been with me for several months now. I love that it's a 10ml sprayer, which is quite generous for a freebie (I must be a very good customer then). I love it so much that I still haven't used it, as if it were something so precious I didn't want to part with. But I have to use it, so here goes.
