S/2 coach bangles

Set of 2 coach bangles. Blue one is played brass with blue enamel. White is plastic with plated brass dots. Both are stamped with “Coach”. Both worn- the plated brass is rubbing off on the blue/gold on the inside, but the blue enamel is in great condition. And the white ones “dots” are turning other metallic shades- but looks very vintage as opposed to worn. Great alone or stacked!
