Touch Up Kits include an Ultra Mark Pen, Graining Stik, And/Or a Fil-Stik. Natural Touch Up Kits include a Graining-Stik and do not include an Ultra Mark Pen. Ultra Mark Pens apply finish color over light scratches and long cracks that go beyond the finish layer. Fil-Stiks are formulated to fill and conceal deeper nicks, scratches, holes, and corner joints. Plastic cards and nylon pads are included with Fil-Stiks to level and clean touched-up finishes. Many of our wood finishes feature distressed patinas with distinctive cracks, knots, nicks, and imperfections that make each piece unique. Fil Stiks are not intended for use on outdoor furnishings.
