Erasable pens aren’t new. Good erasable pens are. Most of the ones you can find at your local drug store are junk and leave clear evidence of your writing after you’ve “erased” the ink. These Pilot FriXion Erasale Pens finally get the idea right. The thermo-sensitive ink in the different pens (and highlighter) allow you to use the erasing tip to clean up any errors in your writing. They’re available in a few different forms – ballpoint, fine point, and clicker – and will help you out so your writing doesn’t look like a 14-year-old’s on Twitter.
