BUTTONS (6) 1/2" round black 4 holes

BUTTONS (6) 1/2" round black 4 holes (Set of 6) 1/2" round black button with 4 holes. Material seems to be a type of plastic. 2 of the buttons have a partial coating. The other 4 are completely matte. Very flat on both sides, not a distinct back or front. This was from a mixed bag. Year, brand, and materials are unknown; the descriptions are my best guess. If there are specific angles you'd like to see that have not been included, please make a request in the comments.
