The first layer of Ambra Oud by Erbario Toscano is dark oud and warm amber. A caramel nuance softens the woods with a creamy, measured sweetness.This is the on-demand format of Ambra Oud, intended for a quick refresh rather than constant diffusion. The catalogue entry is for 100ml. Choose the corresponding diffuser when you prefer ongoing rather than occasional fragrance. Store the bottle upright, with the cap or nozzle secured.
