How to use: Kids can start by having Optimus Prime in either robot or truck mode. When they want to transform it, just perform the easy one - step conversion. For example, if it's in robot mode, use that one step to turn it into a truck. It's very simple and suitable for preschoolers. Note: Keep small parts away from very young children to avoid choking hazards. When playing, try not to use too much force on the conversion parts to prevent breakage. Maintenance: If the toy gets dirty, you can use a soft, damp cloth to gently wipe it. Don't soak it in water or use harsh chemicals as this may damage the toy.
