Noodler's Ink, Blue Ghost

Do you like the original inks?
Do you want to write with an invisible ink?
I've found your perfect ink for your fountain pen!
It's from Noodler's Ink and it's called Blue Ghost, it's an invisible ink that can only be seen in a black light!
When you look at the paper without the black light, it seems the page is blank; it's really funny! :)
They have a lot special inks, and every ink has his own history... don't doubt to take a look at their page!
