i have a erasable pen (via friction thing)

Fun fact: these pens don't actually erase, they just use heat to become invisible

Not same diff at all

The erasing can be reversed with cold

Don't write secrets in erasable ink

Oh, I didn't know it could be reversed. My bad.

It's neat for writing fun secret messages. Just hold it above your stove or other heat source to easily erase the entire page, then have the recipient put it in the freezer a bit.

But yeah, don't write anything too important.

They are so freaking good. I can't just write the letters in the right orders for the life of me

That is my daily driver pen type too
