Pen of Invisible Ink
This pen looks like an old-fashioned calligraphy stylus, but contains its own magical supply of black ink. Any letter printed with this pen appears normal until the user speaks a name and blows upon the paper. Once spoken, the ink fades and can only be viewed by the person who was stated at the time of writing. If the name is not specific, then anyone with the same name will be able to read the message as normal.
A read magicspell will indicate that invisible ink has been used, but will not reveal the message. It is possible to create a nonmagical chemical compound (Craft [chemical] check, DC 25) that, when spread over the surface of the paper, reveals the message written in invisible ink.
A pen of invisible inkholds enough ink for 50 messages.
