Using your S.H. Figuarts Killua action figure is easy. First, pick the face and head parts that match the scene you want to create. Then, attach the right hands for different poses. If you want to show off Killua's electric Nen abilities, just add the electric effect parts. When handling the figure, be gentle with the small parts like the interchangeable hands and face pieces to avoid breakage. Store the figure in a cool, dry place away from direct sunlight to prevent any color fading or damage. If the figure gets dirty, you can use a soft, dry cloth to gently wipe it clean.
