Our stamp-action device fills in scranton bubbles in one press, negating any time needed to fill in bubbles on exams in regular classrooms or even the ACT/SAT. The time saved with the Presto Pen allows for a much more efficient test taking experience and ultimately can improve a student's ability to score on these tests. Our company surpasses any normal pencil or pen brand when it comes to this kind of test taking because of its design. This pen eliminates blank bubbles, incomplete bubbles, and other improper marks.
