The Pulaman was designed as disposable fountain pen.
This is one of my favorite pens for journaling and all-purpose hand writing. I've never found another pen quite like it! Its unique nib gives you infinite options of fine or boldness of stroke, and it has a satisfying, slightly scratchy feel as you write. It's not for those of you who recoil from the slightest sense of grit on the page, but for the rest of us it's just the thing.
(This listing replaces former listing for the Pentel Stylo Sketch Pen. The Pulaman is virtually indistinguishable from the Stylo you may already know and love.)
