There is no reason to replace or re-stain your entire hardwood floor or wood furniture when this little pen can fully reverse almost any damage or blemish. Just gently shade in your floors problem areas and the pen will do the rest. The scratch fix pen contains actual stain, not ink, so it soaks into wood for an even and consistent color that blends with the surrounding wood. It will also never run or smear, so you can wax it or clean it just like it was never there. The unique filter on the tip of the pen dispenses stain at a stable, balanced rate, making it nearly impossible to apply too much. And thanks to its instant drying nature, you wont have to keep returning to the problem days apart to apply new coats to see if the jobs getting done. The filter also gives the pen an extremely long lifespan typically over 1,000 applications.
