Every business needs to have a sign telling their customers if they're open or closed. This practical sign has one side printed OPEN and the other printed CLOSED. The 2 suction cups supplied are ideal for hanging this sign on a glass door or window. The sign itself has 2 holes on the top which will hook on to the suction cups and can easily be lifted off and turned around as desired. The material used on the sign is 0.75mm thick solid plastic not a laminated card so it should have many years of use.
