Each Ostens 'Impression' is a fragrance created as an ode to a single inspirational ingredient. Here is patchouli. Melting wax. The resinous dust from a violin's bow. Crushed biscuits, cooked molasses. Old bricks, decorative tiles, worn stone floors are just some of the references said to be conjured up by this scent by Domitille Michalon-Bertier.
