Louisville Basketball Glow Cup UNPUNCTURED University of Louisville Cardinals.
When the vials are broken inside of the cup the liquids mix and create a compound that glows. The patent number for these cups is 6062380. I have 2 of these cups, rare already, that each have fully-intact vials. See photos. 5.6” tall, 2.25” in diameter at the base, and 3” in diameter at the top. I will ship securely as to not have the vials break in shipping. ..
