Vintage Plastic Bangle

This is the latest addition to my plastic bangle collection. It is rather big - almost 4 inches and quiet heavy: more than 130 grams! It has some signs of wear when looked at with a magnifying glass and I am pretty sure that it has a bit of age. I am not too sure about the material. I think it is plastic but it could be something else.

It feels and looks cool. Too bad that I don't wear bangles in the winter much because they are hidden by the big sweaters and massive jackets!

Thanks for looking:)
