It's Hip to be square.
Geometrical square vintage white plastic ring
1/2 by 5/8 by 1/2 inch high
Square looks a bit off kilter, so it's not a perfect square measurement wise.
No sharp angles, corners are blunted.
The material is vintage plastic

In good condition with some metal wear on the gold tone shank and ring.
Ring shape also seems a bit misshapen

Shape: Square

Size: Adjustable
