Great gift for the golfer and perfect prize for golfers. When you hit the green and want to clean your golf ball prior to putting, hold its spot by placing one of these handy-dandy super bright multi-colored LED Ball Markers down. Sold in packs of 9, the battery-powered white pods with built-in brightly colored red, green and blue LEDs ensure your ball's place is never lost. To turn on, squeeze pod once. Continue to squeeze to cycle through the 3 distinct light modes: fast flash, slow flash and slow morph. A final squeeze turns the pod off. Enjoy up to 8 hours of illumination. Batteries are installed & included (not replaceable).
