Shadeline smooth, flat composite plugger. Diameters: 1.6 mm and 1.1 mm. The hand-finish on our composite instruments allows as small as possible a contact area between composite and instrument, lending practitioners greater fluidity of movement. X-Shadeline: This new instrument range has the very latest high technical coating. It has optimal friction coefficient and resistance to abrasion. Furthermore, the black finish means the user is not irritated by reflections from steel. The Shadeline instruments make for easier handling and more fluid shaping of composite materials.Caution: Clean the tip immediately after applying composite to remove possible film. Do not clean with a hard bristle brush. Fine scratches make it easy for composite to adhere to the surface.
