The Frixion Erasable pen is an erasable gel pen. The Frixion uses thermochromic ink in order to "erase". Included in it is a hard, rubber tip at the end. The heat from the friction (hence the name) generated using the rubber tip is used to heat the ink until it turns clear.
Well, does it work is the question? Yes. It writes fairly well, and with a bit of pressure will write without much skipping at all. However, if you are looking for an erasable pen that acts more like liquid graphite then you might want to beware of this pen.
It's very hard to get thinner lines with the Frixion that you can get out of a sharpened pencil or lead pencil because trying to write that lightly will cause more frequent skipping. This means that this pen would also be a bit of a problem for anyone who's trying to use it to ink a sketch or do any detailed inking.
The pen also had a tendency to let out more ink than needed, however, it's usually only a small drop and doesn't affect it's performance, although I'd recommend anyone using it have a quick writing hand. The pen erases pretty well, provided that one didn't press too hard, and manually warms up the eraser before erasing the ink, it basically erases clear, with little to no shavings to brush off the page.
Overall the pen gets a 3.7/5. Better than most "erasable pens" which become permanent over time, but not enough to replace a standard pencil
