What is a Kameia?

A kameia is a short Kabbalistic text written on klaf. One of my customers brought me one to fix. The only problem with fixing a kameia is that you have to understand the kavanos of a kameia. My Rav told me that I shouldn’t touch it. This particular kameia was given to the owner by a very reliable source, but you should know that there are many fakers who have their hands in your wallet.
