Model: Multi-color Flashing BallsQuantity: 6pcs/setFeatures:- Great Performance - far superior to "glow stick" balls- Flashes BRIGHTLY for 5-8 minutes after being hit- LED 7-Colors Flash is impossible to miss - find it anywhere!Function:Twilight golf ball has revolutionised playing golf past dusk and at night. Up until now, playing at night meant fighting with an unbalanced ball with a stick stuck in the middle. Not only did they fly just about anywhere they weren't supposed to, they were notoriously short and usually only bright for a few holes. With the Twilight flashing golf balls, night golf is tons more fun. After being struck, the Twilight starts flashing brightly - VERY brightly for 5 minutes. Whether you play in night-time tournaments, or just want to make sure darkness does not run you off the course with a late tee time, the Twilight golf ball is great for any bag!
