They can be used INDOORS or OUTDOORS on ANY smooth DRY surface. They will work great on the front / back door or windows.
They were printed on 3M Air Release Vinyl material and then laminated with a crystal clear laminate to last MANY years.

Just clean the surface first to ensure that it is free from: grease, dirt, oil, etc... also make sure that the surface is dry.
