French Ivoy is Celluloid and has nothing to do with being French or Ivory.
I did not voice any opinion in what the ieton was made of; only showing what the seller claimed and, when I saw the sale I had passed on it.

Westen should know what it is.

When I bought this the seller listed it as Bone and only showed one side which I thought was Celluloid.

When I received it I still thought it was Celluloid... Then I turned it over to s ee it was correctly described as Bone...
