Which Should You Buy?

Our Verdict - The Library Collection Opus II
This one's a proper grown-up scent, polarising some with its classic barbershop vibe but adored by others for its sophisticated, masculine charm. A complex fougère that blends tradition with a refined touch, though its subtlety won't please those craving a powerhouse beast.
Favourite
Our Verdict - Diadem
Divisive yet divine. Diadem straddles the line between established Middle Eastern incense profiles and something entirely unique, with a stunning, evolving dry down that some absolutely adore, and others find a bit too familiar. High quality, great performance, and a touch of that Thameen magic.
