Un Bois by Obvious Description Un Bois Eau de Parfum by Obvious is an olfactory expression of wood in all its forms: fresh, solid, and dry. This unisex woody fragrance evokes the solidity and character of classic instruments like Fender or Gibson guitars, played at full volume. Ambroxan adds a modern and captivating touch, while the blend of sandalwood, cypriol, and cedar imparts an indelible sense of power.
