Fadable Highlighter Pen

Dear Sir/Madam,
Im looking for a highlighter pen that fades after a period of time.
For example, you highlight a sentence in a book, then after a period of 6 months without using the book, the highlighting ink is no longer there?
Just interested if this has a possibility to be manufactured.
This must be able to be shipped to Australia.
Use : Office & School Pen
Promotional Pen Type : Multi-Functional Pen
Material : Plastic/Bamboo/Rubber/Metal
Novelty : Yes
Kind Regards, Amber.
