Why Fountain Pen is preferred

I like to use Fountain pen since some 30 years ago as it is stylist, classic to carry and Most of all, can produce better hand writing.
Some people criticize that Fountain pen is troublesome, leakage of the ink, not easy to use, have to go with bottle of ink.... All these criticism is in fcat the positive side of them.
Good functional Fountain Pen never leak, most of the fountain pens can be used on board aircraft, we can create more stylistic hand writing, it is cheaper to run with ink.
Moreover, it is fun to use...
I always carry two fountain pens everyday.
