Glowing Highlighter Pens

Origin
Highlighter pens are colorful, water-based ink pens used to provide stark contrast to written words. They are used by students and researchers to emphasize the importance of a particular passage within a text.

Usage
When something is marked with one of the pens the entire object will take on a brilliant glow that shines in the dark. There is no need for neutralizer, as a quick shower will wash off the glowing effect.

Collection
Collected from a college dorm-room. During a coffee-fuel study binge, a student went nuts and highlighted his entire room. The event created the artifacts. As one of the most harmless artifacts in the Warehouse, Claudia likes to use them to throw rave parties.
