Im about the send out my first gumpast topper and want to send a emergency repair kit just in case. What would you include in the kit?

For most gumpaste toppers (like a number for a birthday cake), I always make two of them, just to be safe.  It's tough to repair them, once they break.  Make sure the topper is not inserted into the cake during transport.  That's just asking for trouble.  Hope that helps!
