I succumbed to temptation and purchased a Sharpie Liquid Pencil. I keep a notebook with me every day, so I love my paper and pens. Typically I use a Pilot G2 07, but am willing to test other pens. Unfortunately, I’m disappointed with the Sharpie Liquid Pencil.
It has a pronounced pencil “feel” when writing. That is, you’re aware of scraping away at the material in the cartridge as opposed to the roll of a ball. That’s fine. In fact, it’s how a pencil should feel. It also erases as effectively as a number 2 pencil.
The problem is the inconsistency with which the material is left on the page. In the photos below, I’ve written the top line with the Sharpie and the bottom with the Pilot. While the Sharpie’s output is acceptably lighter in color, it looks like it was put down by a pen that’s about out of ink. Pen strokes are often broken by small gaps, which is distracting.
It’s an interesting idea and I hoped it would successfully merge two devices that I typically dislike — mechanical pencils and erasable pens — into one that I’d love, but that’s not the case. Unfortunately, I can’t recommend the Sharpie Liquid Pencil.
