Stock up for battle and light up the sky with the Nerf Pro Gelfire Nightfall Hopper and 5,000 dehydrated glow-in-the-dark tracer rounds. The hopper charges these Nerf Pro Gelfire rounds to make them glow. Add water to hydrate the rounds, pour them into hopper, then switch on the hopper to make the rounds glow. When fired from Nerf Pro Gelfire blasters, the hydrated soft super absorbent polymer projectiles fire at a high velocity and burst on impact. No need to pick up rounds! This refill keeps you in the game with an additional hopper and plenty of rounds. Hopper has 500-round capacity. It's a great gift for teens to keep them stocked up for Nerf Pro Gelfire battles. Eyewear required (not included). For use with Nerf Pro Gelfire blasters that use removable hoppers (each sold separately, subject to availability). Outdoor use recommended. For Ages 14 and up.
