The invention is an erasable soluble graphite ink that liquifies with the consistency of a number 2 pencil and allows you to fill in circles more easily.
This soluble can be adapted to an existing pen-like instrument.
With one motion of the dauber, repetitive circling – typically done with a standard pencil – has been eliminated.
Circles can now be filled in up to 5x faster!
When the dauber is applied to a writing surface, it provides for a machine-readable pattern.
The composition may be erased using a standard pencil eraser and remarked if necessary.
The Liquid Erasable will be ideal for all standardized testing, voting, lottery cards, or anything with a scantron-like application.
