This is a manual display case for destination signs. It is made of wood and can be rotated using both knobs. As it is handmade, it is not a perfect item, but I believe it is sufficient for displaying and enjoying your favorite signs. It can accommodate signs up to 700mm wide. *The signs in the photos are for reference purposes only and are not included. I would like to pass it on to someone who will cherish it. No claims, no returns, please.
