invisible pen mq-826

Write a secret message or use the regular black ink pen--this pen does it all! This invisible ink pen lets you write messages without leaving a trace. Use the pen's imbedded blacklight to read what you wrote. Kids love using this for writing secret notes or for diaries.
Features ink made of special high-brightness compounds that are invisible to the naked eye, but magically illuminate when exposed to a blacklight.
Conveniently located on the opposite end of the pen, the blacklight allows you to read any marks that you have made.
