Clamshell sizing questions

[MarcelloD]

For making customs with my own clamshells, what should the dimensions be for the display card/backcard?
I would like to get some done at a print shop so exact measurements would be nice. Thanks!

This question is confusing. Sounds like you're asking what the card size should be for "your clamshells". If you are asking what clamshell card size should be, that depends on the clamshell you are going to use. I will guess you plan to purchase clamshells and make custom cards. The answer is to purchase chamshell first and make the card to fit.
