Using this Jurassic World Indoraptor mask is easy. Just put it on your head and adjust the strap at the back to make it fit comfortably. Once it's on, you can start your dinosaur role - play. The red light on the left temple will project a target, so you can track your 'prey'. Open the jaw to hear the realistic dinosaur roars. When you're done playing, take off the mask gently. Remember, this mask is not for children under 36 months. Also, it has a button or coin cell battery. If swallowed, it's very dangerous, so always keep it out of reach of small children. Check the battery regularly and replace it according to the instructions. Keep the mask in a dry and clean place to maintain its quality.
