It used to be your signature was enough, but with fraud more rampant than ever, Montblanc have come up with a very expensive and unique solution. Personalized Ink DNA. If that’s not enough, they give you an exquisite gold plated, diamond encrusted Meisterstuck pen to deliver the ink. If you have enough money to purchase this set, then you probably aren’t signing anything yourself, but damn does it look great!
The ink has a special botanical ‘DNA’ which can be identified and traced back to the owners ink and pen. Since I’m a bit scared of the price of the pen set, i can’t imagine how much it costs to extract and match pen DNA if ever there is a dispute. Regardless- I still want one.
