They pulled the trigger so you can push the pin. This set of 8 Bullet Casing Push Pins come to you and your cork board from real, once-fired, American-made 9mm bullets.

Stick one in your eye or swallow it down with some chocolate milk, and you’ll probably find that even out of commission these bullets become real unsafe real quick.
