Cartier Pasha Platinum Rollerball pen

Platinum limited edition Fountain

Platinum has produced only 1000 such pens and now the production have been stopped. 
I strongly recommend this pen because of several reasons:
If you see this pen you will find it as a normal pen. But if you touch it, you will be surprised to feel its lightness and strength. It is very light (25g) and strong (10 times stronger than iron). 
The new technology used in this pen of Special Carbon which is used in the Space stations. This makes the pen very unique from others. Japanese Platinum pen borrowed this technology from Torayca,inc.
A lot of research has been made in Japanese university by famous professors and the proper need of a writer is taken into consideration before implementing this technology in this respective pen.
