The MiniMax case is our smallest rave glove light and fits very well in any type of glove. This new light uses 1620 batteries for longer use and save you money on batteries. With this new smaller in size light the Mini Max will allow more freedom in finger movements giving users a better light show! Made of two types of plastic. The finger or top side is soft rubber to allow the light to stay snug to your finger. The bottom side is hard plastic coated with rubber to allow a tight battery connection but a soft surface.
