Erasable vs. Non-Erasable Pens

Might be the dumbest question of all time… Are we allowed to use non-erasable pens? Put another way, if the pen isn’t recognized as being erasable by a proctor, is it still considered a permissible writing instrument?

Yeah you can use either erasable or non erasable pens…your choice as long as it is blue or black ink

either way i’ll be taking both sorts. probably 4 of each. who knows what the proctor decides as legal…
