No idea if it’s heretical in the fountain pen world, but I’m a fan of Pilot Varsity disposable fountain pens. They come in both fine and medium points and a variety of colors. One upside is I always know which pen is mine since I’ve never run into anyone else using them.
I also have some expensive fountain pens, but don’t take those to work.
The Varsity pens are the only fountain pens that "just work" when I use them. Any other ones I own (Parker, Monteverde, Cross) seems to get dried up if they sit too long. My only complaint about the Varsity pens are they are too light -- I like a bit of weight to mine.
It's possible. Another factor is simply how air-tight the seals are. My older fountain pens tend to dry out faster than most modern ones. There are also some pens (Platinum 3776 for example) which are designed to virtually never dry out.
Possibly, but I've used Noodler's ink in them and it doesn't dry up either. (I left one sitting for nearly a year and started hard but would otherwise write fine. Back to normal after I cleaned it.) I suspect it may be the feed they have.
I will echo the Varsity as a great daily. Its the only fountain pen the office supply place at work stocks without a special order too. They don’t leak, ink is smooth, and it comes in purple.
Those things are wonderful! If you want to move on to a refillable fountain pen, the Pilot Prera and other "lower-end" Pilot pens provide a similarly nice writing experience with a dash more style and refillability.
