A light knock on wood

Amber answers the door as

A metal hinge turns

Ysamber® K is a powerful but subtle woody-amber base note, if the oxymoron makes sense. It smells warm and fresh, woody and ambery with a metallic tinge. It’s a bit musky as well, like the pages of an old paperback book. It’s not aggressive when smelled on its own but will make its presence known in a blend, and can be used at up to 10% concentration in a perfume.
