Sold in an assortment of 3 colors per dozen, and shipped inside a nice pop-up display As a student who loves sports, I’m always looking for new and fun ways to keep playing my favorite games and stay active. That’s why I was so happy to find the Light Up 5 Inch Spikey Football, which is the best way to make a spiral throw. I knew this football was something special as soon as I received my package. The length of 5 inches is perfect for my hands, and the soft material makes it easy to hold and throw accurately. But the real magic is in the ball’s surface, which is covered with hundreds of tiny spikes. Every time I throw, I can feel the spikes digging into my skin and giving me more grip than I thought possible.
