Launched in 2010 by M. Micallef and crafted by Jean-Claude Astier, No 51 is a Floral Woody Musk fragrance that embodies the essence of understated elegance. The composition opens with zesty lemon and mandarin orange, providing an invigorating freshness that cuts through the powdery base notes of ylang-ylang and jasmine. As it settles, black musk adds depth, creating a warm and enveloping finish that lingers on the skin.

Application Tips
No 51 is best applied sparingly to the pulse points. The citrus notes are bright but fleeting, so it's the warm musk that carries the scent throughout the day. This fragrance reads better close to skin than in a room, making it ideal for intimate settings.
