Using the Nerf N Series Infinite Blaster is easy. First, load the N1 darts into the 40 - dart battle belt. You can also keep some extra darts in the 16 - dart storage area on the belt for quick reloads. To fire, use the pump - action mechanism of the blaster. As you play, keep loading darts into the belt to maintain continuous play. Remember, this blaster only works with Nerf N Series N1 darts. When it comes to safety, make sure to play in a safe area away from breakable items and people's faces. Also, this product is suitable for kids aged 8 and up, so keep it out of reach of younger children. For maintenance, store the blaster and darts in a dry place. If the blaster gets dirty, you can use a soft, dry cloth to clean it.
