As someone who played a lot of FFRK, seeing these lights was a must be. I love how you can line them up to make it look like they are walking somewhere or put them on shelves in a way that makes it look like they are climbing the shelves. It takes 3 AAA batteries and let's you do a "bright" or "normal" setting. I prefer the normal if only to preserve the batteries. Really great quality and not overly large (~ 4 inches tall). Highly recommend if you're a fan of these characters.
