These ninja posters and prints are super easy to use. Just pick a nice spot on your wall, like in your bedroom or living room. Then, use some tape or wall hooks to hang them up. When it comes to cleaning, you can gently dust them with a soft cloth. Avoid using any harsh chemicals or scrubbing too hard, as that might damage the print. And be careful not to expose them to direct sunlight for too long, as it could fade the colors over time.
