The Force FX Lightsaber Contstruction Kit gives you everything you need to create your own blade. These Master Replicas Lightsabers come with parts to make hundreds of different saber designs. The blade color can be switched between red, green or blue thanks to its tri-colored LEDs. Like other Force FX Lightsabers, it features authentic movie sound effects for power up/down, idle, swing and impact movements. The sounds even change depending on which blade color you choose.
