Using your SH Figuarts Kamen Rider Valen in Chocodon Form is a breeze. You can easily swap out the optional hand parts to pose him in different ways, whether it's for a fighting stance or a more dynamic look. When handling the Valen Buster, hold it firmly by the handle. As for the optional hands and Gavv GaBlade for the Kamen Rider Gavv Poppin Gummi form, just gently attach them to the respective figures. Remember, these are collectible items, so keep them away from rough play to avoid any damage. To maintain the figure's quality, store it in a cool, dry place. Avoid exposing it to direct sunlight for long periods as it might cause the colors to fade. If it gets a bit dusty, you can use a soft, dry cloth to gently wipe it clean.
