Set of 4 bangles

Set of 4 bangles. Three are 1/8 of an inch wide, one is 5/16 of an inch wide. All 4 have a 2 3/4 inch diameter. The 5/16 bangle does have a few minor scuffs and scratches but nothing noticeable unless you are looking at it up close(See last picture). No sure what they are made of but definitely not plastic.
