Like writing in pencils but don't like the hassle of their breaking leads? Sharpie's Liquid Mechanical Pencil is the answer. The tool, looks, feels, and writes like a pen, but it's actually liquid graphite that's coming out of that tip. No more need to sharpen pencils or replace leads in propelling pencils.
This has the advantage of being able to be erased/rubbed out for about 1 day after the initial writing and then it fully bonds with the paper to create a piece of pencil work that wont smudge over time.
