Navy Blue 1940s Galalith / Casein 5cm Belt Buckle

A deep navy blue.

Made of hard and durable casein plastic, and slightly curved so it sits well on a belt.
It's 5cm tall, 4.5cm wide and the aperture is just over 3cm tall, each side is 8mm wide.

one of them has a prong - let me know if you’d like this one.
