Had the pleasure of seeing this pen today
It does appear non-attractive in pictures as a previous thread consensus indicated BUT in real life it is one magnificent piece of art!
The mother of pearl is concave to fit the surface of the cap. It took very special effort to find pearls that have that natural curvature.
The barrel resin is see-through and you can see the mechanism moving.
The gold body and overall design of the pen is very 'organic' as the boutique manager said in his own words. It felt like something made by nature.
