This FriXion Ball Clicker US erasable gel ink pen is retractable, with the clear clip serving as the clicker for extending and retracting the tip. The top end of the pen has a rubber "eraser" colored to match the body and ink color.
FriXion ink is a thermosensitive ink that can be erased by rubbing. To erase, use the special rubber “eraser” tip at the top of the pen and watch the ink cleanly disappear.
Interestingly, erased ink reappears at temperatures below 14° F (-10° C). A freezer is cold enough to make this happen. It is like magic ink for adults! Due to the thermosensitive nature of FriXion ink, we advise against using it for mailings, or leaving the written materials in hot cars or in environments that expose them to a lot of friction.
