These 'The Christmas Experiment' posters and prints are super easy to use. You can hang them on your wall using regular wall hooks or sticky tapes. For best results, place them in well - lit areas like living rooms or hallways. When it comes to maintenance, just use a dry cloth to gently wipe off any dust. Avoid getting them wet as it might damage the print. Also, don't expose them to direct sunlight for long periods to prevent fading.
