Currently Available Shell Colors
National Audio produces your duplicated cassettes in Tabs-Out shells to protect the recorded program from accidental over-recording. Shells listed below are all Tabs-Out. You can purchase Tabs-In shells in a few colors for individual recording in the products section of this site.
PLEASE NOTE: Select a shell and imprint ink color combination with this in mind. Most ink colors are translucent and will combine with the color of the shell in appearance when imprinted. White, Black, and metallic Silver and Gold are the few inks with enough opacity to hold their color alone. For an additional charge, a white ink base can be used to make the other ink colors stand out better. Please ask if you have any questions.
