Lively forest green Brown 1940s 4.5cm Buckle

A glorious marbled forest green colour

Very shiny and full of surface variations - characteristic of this kind of vintage plastic - each buckle is a little different.
A simple buckle but with an edge of attitude.
They are 4.5cm tall, 3.7cm wide and
gently curved.

The internal apertures are 3cm by 8mm

They were found in an old warehouse - excellent unused condition.
