These scene setter wall decals are an awesome decoration for under the sea, sea life and other sea themed parties! This wall-decal is 4' x 30', so if you wanted to cover 8' of height you would have to purchase 2 or cut this one to fit the right proportions. These wall decals feature an underwater view with bubbles all over. These are great on their own, and even better with the other decorations, costumes, and accessories in our store!
