The Frixion line of pens is also useful for this. They might be somewhat limited as to what you can get outside of Japan, but a site like Jet Pens should be able to fix any deficiencies. (Eg: didn't know that they made highlighters with Frixion ink until a recent trip to Japan, where they have these pens literally everywhere)
- rhinoceraptor 10y agoI've heard horror stories of students using those on an exam, and the teacher leaving the exam in a hot car, which 'erases' the heat sensitive ink.
- urs2102 10y agoThese are the only pens I've bought through high school and university. It strikes the perfect balance between easy erasability and visible ink (luckily going to school in the northeast, I never had the overheating in the car issue).
