These are my favorite pens I've ever used. Why?

- The eraser literally never runs out. I've had 1 of them for years and gone through 5+ ink refills

- They actually erase well with very minimal smearing unlike the old "erasable" pens of the 2000's

- Writing in ink while having the erasability of a pencil is great

- The ink does disappear in high heat, but I have never lost anything important. I can almost always get it back using the freezer method

Highly recommend!
