The Scent: With Petrichor, we’ve captured that very special earthy scent created when rain falls on dry soil, so you can step right into your own TARDIS without Amy’s password! For the girl or boy who’s tired of waiting, Demeter’s Petrichor fragrance allows you to travel through time and space straight to the refreshing smell of earth after rain.

Now, the wait is over!
