Koken Barber Supply 10 year certificate. In great condition, never used or issued. This is NOS. I acquired some of these from the original barber supply they were sent to. I have them for several models of chairs from the 60’s. If you are looking for a certain model feel free to reach out. This will also ship with its original envelope.
