Using your ZURU X Shot Fast Fill Micro Twin Pack Water Gun is a breeze. First, find a water source - you can fill it anywhere. Dunk the water gun into the water, then pull the hammer. This will start filling the gun. Once it's full, release the hammer to seal it up. You're now ready to blast your opponents up to 26ft/8m away! Remember, this water gun is for ages 5 and up. After each use, make sure to empty any remaining water to prevent leaks. If the gun gets dirty, you can rinse it with clean water. Keep it in a dry place when not in use to maintain its performance.
