Using this Macross DX Chogokin VF - 1A Valkyrie is easy. You can swap the numbered tail fin parts (1 - 5) to change its look. Simply hold the part firmly and gently attach or remove it. When it comes to the weapons and optional hand parts, just plug them in where they fit. For maintenance, keep it away from direct sunlight and moisture to prevent damage. Avoid dropping it or applying too much force on the parts. If it gets dirty, you can use a soft, dry cloth to gently wipe it clean.
