This LAMY Lx ("Luxe") fountain pen features a body made from palladium, a translucent grey triangular grip section, and a black glossy interchangeable steel nib.
There are lot of subtle details on the Lx as an enhancement over the similar AL-star model, including matching metal accents on the cap end and barrel end with a shiny diamond polish, a glossy LAMY logo on the barrel, and the laser engraving on the nib. While slightly different in appearance than the other LAMY steel nibs, they are indeed swappable as well.
