I draw with fineliners, but I don't enjoy writing with them. I honestly didn't realize that folks regularly wrote with fineliners as I've only seen them with art supplies - which would explain why they aren't common writing tools. Most folks aren't seeing them with the stationary at their store.

If you like fineliners, I suggest refillables. I recently recieved these as a gift and have enjoyed them. [1]
