I have for sale 3 pretty bright fluorescent orange colored plastic Vintage buttons. They have a raised edge, 2 holes in the middle and the edges are about 1/8" or 3mm thick. They are about 7/8" or 21mm wide. The color is really hard to take a picture of, laying flat on a white background they look close to my picture but brighter and when you hold them up and look at them sideways they are very bright and fluorescent.
