The Doors Live In Detroit 2 cd disc set. CDs are from my personal collection from smoke free home. I never personally polish cds. Majority of cd disc have normal wear from handling such as placing in and out of sleeves or cases, placing in cd players, etc. which scuffs or marks cds. My cds do not have heavy scratches. All of my cds load and play perfectly with no skipping. I will not accept any returns because of the ease of having a cd copied or loaded onto a computer and then returned.
