Striking Deco Silver Platinum Casein 4.5cm Belt Buckle

A most impressive Deco buckle.
It looks like it's made of molten platinum - wonderful colour variations and depths on the surfaces -characteristic of this kind of vintage plastic.

Each one is slightly different - see last photo.

This buckle is hard and durable and slightly curved.

They are 4.5cm tall, 4.5cm wide and the aperture is 3.5cm tall and each side is 1cm wide.
