Overwhelming, strong, head ache inducing heavy spiced incense. This is not a walk in a french cathedral this is stepping into a smokey room and being assaulted by spiced incense. Maybe incense scents are not my thing, but this is powerful, very powerful. Wear with care, it might do very well in the right environment but you couldn't spray this on any old day.
Hot, dry incense. Just not my kinda thing.
Actually, this one is spelled Rien, NOT Rein.
This scent is a cousin to Passage D'Enfer. It does not have the spice of D'Enfer but still has the haunting floral and incense notes. This scent also bears a passing resemblance to Bois Farine, with just a hint of the "flour" note. I am still trying to pin down the exact notes of this scent.
It is certainly unusual and worth a try just for it's uniqueness. I love it but would save it for an evening out with friends.
