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. Built with no notes, like a building with only structure and no interior, IDKW has been created to layer. The Bergamot accord announces freshness, Vetiver Acetate a thin amber, Firsantol a lingering sandalwood, Iso E Super a radiance, and so on.  IDKW is built to enhance everything else it touches.
