These professionally made double sided Open / Closed signs are manufactured using a 6mm thick rigid white plastic. Due to the way they are made we can offer virtually all the common background colours but all have to have white lettering. The signs measure 220mm X 100mm and are supplied with a hanging cord and window sucker to allow you to position them anywhere that suits you. As these signs are ALL custom made to order, please make sure you include the wording you want across the top and your colour required when ordering. If no colour choice and wording is given we will supply a standard red / green sign as featured in the first photo. If you have any problems or for more information you can contact us on 01773 743399, email@example.com or by using the contact seller form.
