Wow, what a beauty this is! Although unmarked this is a vintage ribbed plastic hinge bracelet made in Western Germany from the sixties.. It features one side that is transparent brown and the other a shiny gold tone. The spring hinge is in excellent condition. There is virtually no signs of wear to this bracelet. My wrist is 6 1/4" and the bracelet is a perfect fit. It graduates in width from one to two inches. A perfect wear with everything bracelet!
