Glow parties are hot, and glasses are a great way to express style. Put on these glowing glasses and really stand out at any glow party - on ship or shore! Easily switch between steady-on and flashing at the push of a button. Lightweight, as the batteries are stored in a separate pack and connected via a thin cable. Add two AA batteries and you're ready to be the brightest nerd at the glow party. We could probably have worded that better.
