At the Mont Blanc Pen collectors Net website

to ensure authenticity of your product, check under the clip on the
cap- there should be an engraving reading "Pix".
Another reference to Pix can be found at Newsnet5.com (WEWS Channel
5 News), in an article titled Store Accused Of Selling Fake Luxury

they state the following:
The clip on the pen given to Cox did not have the markings of a Mont

the inside of the clip.
Based on this information, I conclude that an authentic Montblanc pen
should include a serial number on the clip and the number 4810 on the
nib as described at the Montblanc website.
Also, according to other sources, the letters PIX should also appear
on the clip.
