Continuity mistake: When Elliot's the basketball player, when he scores the slam-dunk and breaks the headboard, he breaks the headboard after the slam as he bounces/hangs off the headboard. But in the replay he breaks the headboard as he makes the slam and then bounces/hangs off the headboard. (00:49:10)
Elliot Richards: You can't give sick people 'tic tacs!'.
The Devil: Sick people have notoriously bad breath, I'm performing a public service here.
Trivia: When Elliot is on the beach, as the devil walks by with two dogs she refers to them as Dudley and Peter, which is a reference to Dudley Moore and Peter Cook - the stars of the original Bedazzled.

Answer: It definitely is a Montegrappa Oriental Zodiac pen, this brand has been making pens in Italy since 1912. I am not sure which of the three red pens in that collection (Oriental Zodiac) is the one seen in the movie, but given its association with the devil, my guess will be it is the Ox fountain pen.
