I've seen some "specialty" permanent marker pens that are labelled as a CD Marker. Now I usually use a regular Sharpie permanent marker, like the industrial markers for marking cartoons and boxes.
Are the special CD Markers just a scam (greater price than Sharpies), or does it really make a difference?? And if there really is a difference, are the Sharpies harmful and have the potential to damage my CD's??
