This is a UNIX umpire indicator. I'm selling it because I never used it. There's a gap at the top, but that's how it came. It hasn't been dropped. Only those who understand are welcome to purchase. [Design] It has a slim design that fits comfortably in your hand and is easy to carry. It's lightweight and easy to handle. It's yellow and easy to see. [Uses] As an umpire's tool for baseball, it's useful during games and practices. It's especially ideal for use in amateur and junior leagues. - Color: Black - Shape: Slim design - Size: Small Thank you for looking.
