The mice look right at anyone looking at you! LOL - Simply pull out your glow stick under and inside the mouse and break it and shake it and place it back inside. There is a glow stick in each mouse. Colors may vary but will be the same in each mouse. You may purchase more glow sticks from our store for future use. These can also be worn without the glowing effect just to tease your friends and even strangers! lol - Please feel free to email any questions you may have. Thank you and have a Blessed Day!
