Atmospheric ozones and ultraviolet light as well as static electricity can be potentially lethal for CDs. These new Corrosion Intercept CD Pockets offer the protection from all three. Your music or your data can be protected from these harmful elements. The translucent archival polyester envelope allows you to see inside without removing the CD and subjecting it to handling or static charge. The static charge generated by walking across the carpet can be lethal for CDs if you touch the top of the CD before grounding yourself. Intercept is ESD safe and will allow you to discharge at a controlled rate, thereby protecting the CD.
