To use your Ragnarok poster, simply find a nice spot on your wall where it can be easily seen. You can use picture hooks or adhesive strips to hang it up. When handling the poster, make sure your hands are clean to avoid getting fingerprints on it. To keep it in great condition, avoid exposing it to direct sunlight for long periods as this can fade the colors. If there's dust on the poster, you can gently wipe it with a soft, dry cloth. And that's all you need to know to enjoy your beautiful Ragnarok poster for years to come.
