Using this product is super easy. First, take out the 4 - inch action figure and the Mechasaur. Let your child use their imagination to pose the figure with its 9 points of articulation and stage battles against Ultron. To build the mech suit, disassemble the Mechasaur and put the pieces together. When playing, make sure to keep the small parts away from younger kids to avoid choking hazards. Also, play on a clean and flat surface to prevent losing any pieces. For maintenance, simply wipe the figures with a dry cloth. Store the figures in a safe place when not in use to avoid damage. Have fun with your Mech Strike Captain America with Redwing Mechasaur!
