Using the T - Rex Anatomy Kit is easy. First, take out the instruction manual and read through it carefully. It will guide you step - by - step on how to piece together the 28 parts, including the bones, muscles, skin, and organs. Start with the basic skeletal structure and gradually add other components. Once you've completed the model, place it on the included display stand for a great show. As for safety, keep small parts away from children under 3 years old to avoid choking hazards. When not in use, store the kit in a cool, dry place to prevent the parts from getting damaged. If any part gets dirty, you can gently wipe it with a soft, dry cloth. Have fun exploring the world of dinosaurs!
