Using these action figures is a breeze. For Ultraman, you can move his joints to create different action poses, like making him throw the Specium Ray. Just gently bend his arms, legs, and torso. For Emi, move her neck and limbs to give her cute gestures. You can swap the eye parts by carefully removing the existing ones and putting in the new ones. When it comes to maintenance, keep them away from direct sunlight to prevent color fading. Avoid getting them wet as this could damage the paint. If they get dirty, you can use a soft, dry cloth to gently wipe them clean. Also, be careful when handling the small parts like the optional hands and eye parts to avoid losing them.
