Belgium ARAMITH Premier Billiard Pool Balls BOX. Maybe balls are Aramith also?

Description

Belgium ARAMITH Premier Billiard Pool Balls BOX. Maybe balls are Aramith also? OK....I cannot determine what the heck I have here.What I have decided is that the box is genuine Aramith.
This auction is for the Aramith box and whatever the balls are, if they ARE genuine you guys will know and we can let the market determine the price.If they ARE NOT genuine you guys will also know, and again, we can let the market determine the price.You are the expert...I know absolutely nothing about these balls. I am being upfront and honest about my knowledge and position.It is not my intention to deceive anybody, it also not my intention to give away valuable product without knowing what it is.This is the only way that I could think of to sell these balls.Any input is appreciated.
Notice the 12 ball has been chipped, this may provide some clues about the material and/or construction to aid in identification.
Please notice the pictures with the genuine Aramith  8 balls.These balls ARE NOT INCLUDED in this auction.I included these pictures to show you that I do have genuine Aramith balls and so these could be also. These balls are available in separate auctions.
This should be interesting...good luck!
