This Alf Head Knocker figure is a great collectible. Just place it on a flat surface like your desk or shelf, and enjoy watching its head bobble. It's a decorative piece, so avoid dropping or rough handling. To keep it looking good, gently dust it with a soft cloth from time to time. Don't expose it to direct sunlight for long periods as it might fade the paint. If you want to clean it, use a slightly damp cloth and then dry it thoroughly.
