The Sharpie Touch-Up Permanent Marker could be one of the most useful DIY tools for the home; they should be shelved right next to your Tide-to-go stick.
If you've ever scuffed, dinged or nicked your dark furniture, you know how aggravating it can be. Sure you can put a little table cloth on top, or hide some things with a vase, but that's like sweeping dirt under the carpet.
The Sharpie Touch-Up Permanent Marker is designed to "touch up furniture, flooring, doors, cabinetry, wood trim and picture frames with a few quick strokes."
BTW, Sharpie now also lets you personalize your own permanent marker; you can add your own text, choose the color and add a little image (6 only cost $11.99!)
