Fucking why?

>> No.9983070

Or, just use a pen. Erasing is for people who make mistakes.

That's why I have to use a pencil. The only people making mistakes are the math department and your parents.

It always makes me laugh that amerisharts use pencils even in college. Here in France they teach you how to use a fountain pen in the first grade.

Yes but it requires a lot of heat and I've never had any problems with it. That being said, I wouldn't keep it under a heat lamp.

Those don't actually erase. It's color changing ink that turns transparent at high temperature (i.e. by either the friction caused by rubbing on it or by leaving it in the sun) but changes back if you put the item in the freezer for a while.

Get your overpriced piece of shit out of here.

>> No.9987542

Those pens use ink that disappear in high temperature. That's essentially how they were designed to work too since the heat from the friction causes the ink to vanish. This is an incredibly risky thing to use in hot climate regions on tests. Imagine your professor leaving the tests in a car on a 100 degree day. When it comes time to grade them your paper is blank.
