These unique Light-up Shoelaces will make your high school students' faces light up with excitement as they light up the night on game days or for school dances. The 24" long white nylon laces have multi-color LEDs inside them! Once the laces are inserted into standard tennis shoes, the LEDs blink and flash with the push of a button! Light-up Shoelaces make cool favors for a 1980s prom or school dance theme, fun school fundraisers, and unique items to stock in your school store and game day concession stands. Laces are sold in pairs and include two CR2032 batteries (batteries cannot be replaced).
