The Avery 3″ Hexabumper is a durable, larger retrieving dummy for land and water. It’s valveless design won’t take in water, and the raised VGrips encourage better holding with less sliding in wet mouths. HexaBumpers’ flat sides promote secure holding as well. Very firm. Available in white, orange and “flasher.” The flasher concept — alternating black and white sides — gives a hi-viz strobe effect in the air to catch your dog’s eye.
