Piranha has an original sci-fi inspired design for one-handed use, and has the same power, speed and range you've come to expect from Gel Blaster products. Includes Gel Blaster water based Gellets (non-toxic, non-staining, non-irritating) that burst on impact and dissolve, ensuring safe and mess-free fun. Its battery-powered design keeps you moving without the need for constant recharging.
