I've used these for years. Table crews vary in the level of attention and putting a coin or extra whistle from pocket to pocket looks awkward and a little shabby and some associations don't want that done. After a few times using it you'll come to realize that the white side is up and the black side is down so you'll never really have to look at it, just touch it during a held ball. Small, easy, and discreet.
