Switching between red, green, blue, and black in one pen is so convenient for color-coding my lecture notes, and the erasable ink actually wipes clean without smudging. The retractable click feels solid, and the refillable D1 cartridges mean I won’t have to toss it when the ink runs out.

I’ve been using this for my weekly planner and the click mechanism feels solid, no accidental retractions yet. Swapping between red, green, blue, and black in one hand during meetings is way more convenient than juggling four separate pens.

The erasable ink is a lifesaver for my planner—mistakes vanish cleanly without smudging the page. Having red, green, blue, and black in one retractable body means I don't have to juggle four separate pens. Just wish the refill cartridges were easier to find locally.
