If your writing has a flair for the dramatic, take your inscriptions to the next level with Elemental Ink Pens. Part magic, part spycraft, and completely awesome, the ink from these colorful ballpoints completely disappears when you apply heat to them! Since paper burns at a temperature about four times hotter than the ink, you can take a flame to your paper and astonish your audience or hide a secret without setting off a smoke detector. But a disappearing act is just half the trick.
