EVA mats are solid closed cell foam and it would be difficult for plastic pins to penetrate, especially since the plastic pins have a dull point. I would recommend the steel "D" Target Face Pins made by Bob's Archery Balls. These pins come in 3 lengths, 1-1/2", 3" and 6". The pins have sharp points and are equipped with a finger lupe for easy removal.
