These are 3 rubber rings that are made of heavy elasticized rubber.
They measure 4" , 5" and 9" in diameter.
They are a brown color.
I am not sure exactly what they were used for.
The two smaller ones remind me of the arm bands men used to wear to hold their sleeves.
The larger one is too big for that.
They may be some kind of rubber belt for vintage vacuums or something like that.
They are in good condition.
