Sharpie Liquid Pencil
The Sharpie liquid pencil is a pen that is erasable up to 24 hours. Sometimes when im bored, i try making my own creations, some similar to objects like this. I based this campaign on the idea that others may try this also, possibly someone in the office on a slow day. So this person has attempted to create an erasable pen but they are too late because Sharpie beat them to it.
