An unprecedented strength fragrance, the Iridium 71% by Tom Daxon is an intensified version, over three and half times the strength of the original, unveiling new layers of complexity. It's the fragrance equivalent of charcoal-coloured cashmere encapsulating all the powdery sophistication from the precious iris concrete but with a strong silvery spine. 71% refers to the concentration of fragrance oil, the number being the maximum allowed under international regulations for Iridium.
