March 21, 2014
These frixion pens are the greatest advance in writing since papyrus over clay
tablets, in my opinion. Color plus eras-ability. And better eras-ability than
pencil. I've read some reviews stating that writing cannot be completely erased.
Here is what I found: Just pressing hard with the eraser leads to mediocre
results. But since it is the heat produced by friction that makes the writing
disappear, I get better results by rubbing fast rather than hard.
