Car flags are a great way to get attention while on the road. To install, simply place the flagpole's clip on your window and roll up the window. Can be used on cars in motion (45 MPH maximum speed). Your artwork will be dye sublimated on super poly knit fabric. 1.5" pole sleeve is closed at the top to prevent the flag from sliding down the pole. The bottom of the sleeve features a leather tab that can be zip-tied to the pole. Complies with Prop 65.
