The I-Sign Display two-sided profiles are for the production of lightboxes, it is unique in that they are very narrow only 50mm thick. For lightboxes we use 3mm organic glass, which is attached with a magnetic tape.
One-sided profiles of the I-Sign Display are used to produce non illuminated advertising. The profile is only 25mm thick, making it look great in the interior. Advertised products will be without the edge and the fasteners are not visible from the outside.
