It could protect your discs from scratches even when they are playing...
Just snap a d_skin onto your discs and they are consider to be protected.
d_skin stays on your discs even while they play which means that your discs are totally readable right through the d_skin.
check out a video about it....
My Comments are, it is really convenient as you do not need to worry about having scratches on your discs. If the d_skin is spoilt, you just need to replace a new one which is a very easy thing to do.
