Watch your students light up with pride and excitement with these unique Light-up Shoelaces. They look like typical white nylon laces, but they have multi-color LEDs inside them! Each shoelace is just over 24" long and can be used to lace up standard tennis shoes. Once the laces have been added to shoes, the LEDs blink and flash with the push of a button! Light-up Shoelaces make a fun elementary school fundraiser any time of year, novelty item for your school store, school carnival prizes, or favors for a 1980s school dance theme! Sold in pairs. NOTE: Two CR2032 batteries are included and installed, but cannot be replaced.
