Hello ,

Thank you for your inquiry regarding our Sharpie® Markers and their use on
CDs.  Sanford has used Sharpie Markers on CDs for years and we have never
experienced a problem.

Generally we do not believe that Sharpie ink can affect CDs.  However,
please note that CDs come in different quality grades; provided you have a
good quality CD, you should experience no problems.

We hope that this information is helpful.  Please feel free to contact us
with any questions.

Thank you for e-mailing us and for your support of Sanford products.
