The Sailor Holy Grail LE Nagahara Sr King Cobra Nib, Only Chance to Own

As all Sailor collector knows, among all specialty nibs from Mr. Nagahara senior, the King Cobra is the most rare and impossible to find nib.  There are only 25 of this pen worldwide and guess what, even less number of owners as some owners own multiple.   You can safely assume, none of the owner would ever let it go.   This is honestly your only chance to own, pass this time, it can be years or decade(s) to see another one.   
The pen is as new as it gets, perfect and flawless.   I am selling as it is, no return.
