Are these Kelly D. Fun Classes? No! They are LED Sunglasses! As fun as fun gets - face lights for the masses. There's nothing cooler than flashing sunglasses. Blinking shades are great for girls or for boys. These aren't really for sun. They're only toys. These glasses fit most in one comfortable size. Freak out your friends with lights from your eyes. They blink or glow steadily. Each one's installed readily with three AG13 batteries and packed individually. Guitar LED Sunglasses are here to rock. Each pair has 2 red, 2 blue, and 2 green LEDs. One size fits most.
