Using this Kiramaizin model set is a lot of fun. First, take out the parts and start assembling each of the 5 transformable vehicles one by one. Once they're all built, you can experiment with different combinations to form Kiramaizin in various modes. When handling the parts, be gentle as they can be a bit fragile. Avoid pulling or bending them too hard to prevent breakage. After you've finished playing with the model, store it in a dry and clean place. You can use a display case to keep it safe from dust and damage. If any parts get dirty, you can use a soft, dry cloth to gently wipe them clean.
