Using the Nerf N Series Flex Blaster is easy. First, take one of the included N1 foam darts and load it into the blaster. Remember, this blaster can only hold one dart at a time. Then, use the pull - back handle to prime the blaster. Once it's primed, you're ready to blast! Aim at your target and fire. When you're done shooting, keep the blaster and darts in a safe place. Avoid exposing the blaster to extreme heat or cold, as it may damage the parts. If the blaster gets dirty, you can use a dry cloth to wipe it clean. This blaster is only compatible with Nerf N Series N1 darts, so don't try to use other types of darts. And always play in a safe area away from breakable items and people not involved in the game. Have fun with your Nerf blaster!
