Blue Twist Plastic Vintage Bangle

Blue bangle with a raised ridge twist design. Very likely c. 1980s, but it’s unmarked so I’m unable to confirm the exact age. As it’s a fairly small bracelet, please double-check measurements to ensure it fits. There are a couple of small, white marks which I’m assuming are dings from being knocked against a hard surface. I also noted some small scratches with my macro lens. Approximate measurements: 2 3/8” diameter | inner edge to edge 6 cm 7 3/8” inner circumference 18.5 cm 5/8” width 1.5 cm
