This is pretty much the coolest dog ball we've seen for playing fetch with your pet. With 35 hours of play time, this plastic LED glow ball cycles through red, green, blue, and purple lights, keeping you and your fuzzy friend entertained. Waterproof and extremely durable, it'll hold up to the best arm or ball launchers around. The unique grooved surface makes it easy for pets to pick up and it floats so your pet can chase it into the pond or lake. Easy operation, simply give it a bounce to turn it on. Automatically turns off after 10 minutes of non-use. Plastic. Hand wash. Imported.
