Easily slide stops on to wires with the Stop Kit Placement System? from NEXADENTAL. Each Stop Kit Placement System? includes Micro Stix, an applicator with a light adhesive tip that picks up and holds a stop. Simply touch the tip of a Micro Stix to the flat side of a stop, then thread the wire through the stop. When placement is secure, pull away the stick. Stops can be placed on wires faster and more easily with Micro Stix than with an instrument.
