Using the Teamsterz Dinosaur Launcher is super easy. Just place the included die - cast car in the dino's jaws and press down on the dino head. This will launch the car forward. You can then see how far you can make it go. When playing, make sure to use it on a flat surface to get the best results. As for maintenance, keep it away from water and rough play that could damage the launcher or the car. If it gets dirty, you can use a dry cloth to wipe it clean. Remember, the styles are randomly selected at dispatch, so if you have a color preference, add a note to your order. Have a great time playing with your Teamsterz Dinosaur Launcher!
