For those who value the sleek and silky writing style of a classic gel pen but would never risk using one in an official examination, the Pilot BX V5 is your answer.

The erasable pens I remember using when I was in high school in the late 2000s were laughably bad. They required a lot of pressure to transfer ink to paper, and even then, the ink came out faded ...

The pens cost hundreds of dollars; the refills, about $12. You can cut down a Mont Blanc refill with an exacto-knife and reap all its benefits inside an inexpensive Pilot G2.
