SlickBands non-stick matrices are the first Tofflemire-style bands to virtually eliminate the problem of difficult to remove matrix bands. A micro-thin coating bonded to either dead-soft or regular stainless steel reduces bonding agent adhesion by a whopping 92%. Use dead-soft green bands when contact is completely broken with adjacent teeth for maximum burnishability. When contact is NOT broken with adjacent teeth, use regular grey bands. Full Kit contains 300pcs bands in 9 sizes, including Right Curve and Margin Elevation, 100pcs G-Wedges in 4 sizes, 1pc PerForm contact instrument for small cavities and 1pc PerForm contact instrument for large cavities.
