FriXion ink is a thermosensitive ink that can be erased by rubbing. 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.
