We all remember the first erasable ballpoint pens... the ink was pale and blotchy, and the eraser tore through the page. Luckily, new pen technology has made the erasable pen of today better, brighter, and easier to use!
Many of these new pens erase entirely by friction, due to a special thermo-sensitive ink that comes out bold yet erases cleanly. Because friction is all you need to make your writing vanish, the erasers do not leave any messy residue to clean up. There are even markers and highlighters with this incredible ink technology!
