Using the Kai Brightstar Training Lightsaber is super easy. Just give your wrist a flick, and the 3 - segmented green blade will expand. To collapse it, gently push the blade segments back together. When your little one is done playing, collapse the lightsaber for easy storage. It's small enough to take on the go, so they can have Star Wars adventures anywhere. As for maintenance, keep it away from sharp objects to avoid scratches on the blade. If it gets dirty, you can use a soft, dry cloth to wipe it clean. Always check the lightsaber regularly for any signs of wear and tear, and make sure to keep it out of reach of children under 3 years old as small parts may pose a choking hazard.
