Three sliders are moving in front of a fix background. Since the tracks of the moving sliders have different length, the printed artwork is building itself one by one, covering the background slowly. All sliders can be printed up to 4c picture print. The fix background even on both sides. Thus, three completely different artwork designs can be displayed inside this item. - Kleur: zilver. - Materiaal: Metaal. - Customstariffnumber: 85238091000.
