Elemental Ink Pens: Writings Disappear With Heat and Reappear With Cold

If traditional disappearing ink isn't intriguing enough for you, then upgrade to these cool new Elemental Ink Pens. When you write, draw, or color with these normal looking ballpoint pens, the ink will display as normal. However, if you apply heat from a nearby flame then the ink instantly disappears and then it can be made to reappear just as easily when the paper is placed in the freezer or something chilly is placed on it like dry ice. This process can be repeated over and over again. Available in a variety of colors, these mysterious pens are perfect for sending secret messages by covert spies, writing down hidden passwords in plain sight, making fun treasure maps, creating amazing artwork, performing magic tricks, endless pranks, and so much more.
