This is a 1" metal button pin with a safety pin clasp. Blink-182 was a Southern-Californian Pop-Punk band that was formed in 1992 by Tom DeLonge, Mark Hoppus, and Scott Raynor in the northern San Diego suburb of Poway, California. In 1998, Travis Barker replaced Raynor as the band's drummer. They are currently inactive as a group, as each member pursues his own side projects.
