This instrument is made of high grade stainless steel and is used to develop inter proximal embrasures with amalgam and composite class II restorations. The ends are very thin (0.25 mm) and allow access into hard to reach embrasure areas. One end is positioned 90 degrees to the other to improve use in all embrasure areas. It is essential in developing the proper marginal ridge form. The handle is the ergonomically shaped #6 which is the favorite of dentists world-wide. Shipped in a factory-sealed protective case.
