These fans will fit in any helmet or Mask for any character. They come with an on/off switch that you can mount right to your helmet with the included flush mount switches and are very discreet (you can also mount the switches inside your helmet as well if you do not want the switches to be visible). Hit the switch as often as you like with the touch of your finger and they will click on or off. These fans run with less decibel output (lower sound), have a lower currency rating (uses less battery power) and will run on only one 9-volt battery! Set comes with 2 fans.
