Interestingly enough, the ink in these pens will actually reappear when the temperature reaches below -10 C (under 14 Fahrenheit). A freezer is sufficiently cold enough to make the ink start to reappear, you can watch a video on how it works here. It is like a magic pen for adults!
Because the ink in this pen is thermo sensitive, we do not advise for it to be left in hot cars, used for mailing, or subjected to a condition that exposes it to a lot of friction.

These markers are great!...
These markers are great!
I ordered them pieces by pieces because I'm picky on my color choices also because it'll cheaper for me to do so. The packages came in early as I was really excited to try them out.
Even when it is erasable, they are still markers so trying to erase the mark when the ink is still wet will still smudge them. Also it takes a bit more effort to erase than say... pencil. Also don't use sharp point tools such as mechanical pencil to draw on top of it as the point will scratch the color off.
In general, I'm happy with my purchase and I might get myself some other colors in addition to these
