The FriXion Ball 4 multi pen has a cool, modern look, featuring a subtle geometric dot pattern on its shiny pen body. This retractable multi pen contains Pilot's popular FriXion inks in four colors: black, blue, green, and red. The thermosensitive ink can be erased by using the special rubber "eraser" at the end of the pen. The pen has a rubber grip for comfortable writing, as well as a spring-loaded clip to conveniently attach to your pocket or notebook cover. Extra Refills are available seperately.
