These 'Dangerous When Hungry' posters and prints are super easy to use. Just pick a spot on your wall, like in your bedroom or living room, and hang them up using nails or adhesive strips. Make sure the surface is clean and dry before hanging. When it comes to maintenance, you can gently dust them with a soft cloth. Avoid using harsh chemicals or getting them wet as it may damage the print. If they start to look a bit dull over time, you can re - position them to a different spot to give them a fresh look.
