Use these solid, dense plastic hole plugs to fill the unused binding screw holes left after mounting new ski bindings with a different mount pattern. Plugging the unused screw holes is critical to keep snow and water out of your skis core material which can freeze, expand and cause major damage. Drop a dab of waterproof binding glue into the unused binding screw holes then firmly tap in a hole plug with a rubber mallet. Trim the remaining plug material off flush to the skis top sheet with a sharp wood chisel, razor blade, or utility knife blade. 100 count CLEAR in COLOR.
