Set of 5 vintage bangle bracelets

Set of 5 vintage bangle bracelets. Red bangle is approximately 1 inch wide, navy bangle is approximately half an inch wide, and 3 thinner blue bangles are a quarter of an inch and smaller. All made of plastic. Two of the thinner blue bangles are slightly textured and have some wear from age. I’m guessing these are from the 70s and 80s.
