The 420 is a high-end Monblanc pen - a pen that features a high grade Bordeaux precious resin body and thick gold filled trimmings. The pen is near perfectly balanced. The Bordeaux Resin shines and is difficult to scratch. It makes it look as if the pen was made just recently rather than many decades ago.
The cap has a very nice and distinct "click" sound when opening or closing the pen. It features a stunning super smooth superb 18K 750 solid gold nib. The nib is also semi-flexible; it produces wonderful writing with line variation. Montblanc signature stars are located both on the cap and turning knob. The piston is very smooth, with its original silicone cork and takes a considerable amount of ink.
