Is the SHARPIE marker safe for writing on CDs?
Sanford has used Sharpie markers on CDs for years and we have never experienced a problem. We do not believe that the Sharpie ink can affect these CDs, however we have not performed any long-term laboratory testing to verify this. We have spoken to many major CD manufacturers about this issue. They use the Sharpie markers on CDs internally as well, and do not believe that the Sharpie ink will cause any harm to their products. Sharpie CD/DVD marker has a twin tip for added versatility in labeling CD and jewel cases.
