Product Description
A fragrance enhancer with transparent radiance that gives any perfume a certain, as the French say, “I don’t know what.”
"I Don’t Know What is a wonderful tool for anyone who wants to play around with perfume. Of course it can be worn as a modern wonderfully transparent aroma, but it can also be layered over anything. Often when I leave the house, I will wear a touch of sandalwood, rose, jasmine, patchouli, oud, etc. These oils are lovely but can be muddy and they don’t last more than a few hours. IDKW sprayed over them makes the oil into a PERFUME. It does this because it is made with no notes!
It is a secret combination of materials that perfumers use to highlight and enhance notes in a perfume. A Bergamot accord announces freshness, Vetiver Acetate a thin amber, Firsantol a lingering sandalwood, Iso E Super a radiance, and so on.
It is like a building with only structure—no interior. You can fill in the interior with an oil, a scent you like, even an old scent that has lost its way. IDKW is built to layer and enhance everything else it touches." -D.S.
Notes:
Top Notes: Bergamot Essence
Heart Notes: Iso e Super, Vetiver Acetate
Base Notes: Civettone, Firsantol, Ambrox Super
