To use this action figure, you can change its faces, hands, and even put on the helmet easily. Just gently attach or remove the parts. When handling the figure with red LED eyes, be careful not to press too hard on the eyes to avoid damage. For maintenance, keep it in a dry place away from direct sunlight. You can use a soft cloth to gently wipe the figure every once in a while to keep it clean. If you're not using the optional parts, store them in a safe place so you don't lose them.
