I was sent this great kit to use on furniture. It contains 3 filler sticks and 5 touch up markers. The markers are a little smelly but about the same as a sharpie.
You can use on wood or wood laminates. Find the product here http://www.shoplet.com/Master-Caster-ReStor-It-Furniture-Touch-Up-Kit/MAS18000/spdv
You can apply the marker directly to minor scratches, worn edges, blemishes and imperfections.
The filler sticks are for deep scratches, gouges, nail holes, and cracks. You can apply the markers over the filler and then wipe off with a clean cloth for a quick fix.
