I am a dedicated fountain pen collector and user, but in my line of work there are days when they are very impractical. I'm not a snob, so I won't roll my eyes if I have to use a Bic, but my preference is my 1952 Montblanc 256 fountain pen or 1948 MB 246.
Here is the 256. I like it because it was MB's first venture into a "space age" type design:
My collection focuses primarily on pre-1960 German pens (specifically Montblanc, Pelikan, and Sonnecken), although I have some modern stuff and some vintage Italian pieces. I wish I had some of the stunningly beautiful vintage
Japanese maki-e pens, but those are prohibitively expensive since each one is a work of art. I do have a sterling silver
Namiki Dragon that is very, very nice for being a modern pen.
My fountain pen is a Parker 51 Flighter, with a stub nib, and matching pencil.
VERY nice. I've never had a personal taste for the Parker 51, but the
Flighter is a very attractive pen. I love the brushed stainless steel.
I did manage to learn to decline handing a nice fountain pen to someone as a loaner. If you can't carry a ballpoint in addition for a loaner, you must learn to decline in a polite way. "Sorry, this pen might get ink on you."
I am usually OK with letting somebody jot a note or sign something with one of my fountain pens, but I never loan it to them for very long. I have learned to take the cap off and keep it when I hand the pen to someone. Many of the vintage pens have screw caps, and the value is devastated if someone pulls the cap off and destroys the threads.
I still have a Parker pen/pencil set that used the liquid ink in the little plastic tube but it is no longer made, that I know of.
Do you mean like these?
If so, they are available in most office supply stores, as is a limited selection of bottled ink. If you have a fountain pen that can use botteled ink, though, there are some
killer offerings in ink color if you know where to look.
