Using this NERF Iron Man Repulsor Blast Gauntlet Toy is easy and fun. First, make sure you have the gauntlet on your hand. Then, pull back the primer handle on the gauntlet. This mimics Iron Man's signature Repulsor Blast move and allows you to launch a NERF dart. There are 3 NERF darts included in the set, but you can buy additional ones separately. When playing, always remember to follow the safety rules. This toy is a choking hazard for children under 3, so keep it away from them. Also, never aim the dart at eyes or face. Only use official NERF darts to ensure safety, and don't modify the darts or the dart blaster. To maintain your toy, keep it clean and dry. Avoid dropping it or subjecting it to rough play that could damage it.
