Billiard ball carrying case: Mckernan style?

[PhilosopherKing]

Can anyone shed some light on this?

I’ve never seen another like it.

Thanks

Is that the right size for three carom balls?

It’s two separate compartments. One side holds two balls and the other holds one.

I have seen camera lens cases similiar to that also. Mystery item of the week????
