I called CRK once on this subject and, IIRC, one of the pretty (and capable) girls on the phone told me that if I send in my knife for a spa job/inspection, that they do have a capability of verifying the folder and supplying a "replacement" birthcard. And boxes and blue cloths are easy enough to find. Not a problem. I believe that CRK will return your spa-job folder in a "box" (perhaps without specific labeling). They might sell you a blue microfiber cloth also. If not, they can be found on the "water."
I THINK I'm right. Good thing, too, as last wk I bought a small Sebbie that came with nothing other than plastic wrap. But, I knew that in advance; no foul.
