This dinosaur knockout wall decal would be a great border in your kid's bedroom or playroom. Knockout simply means the dinosaurs will be cut out of the border & the color of the wall will be shown, as in the main item image. You will receive 4 strips that are 5.75in. tall & 39.25 wide that will give you about 10 feet of border in the color of your choice. Installation is as easy as overlapping each strip about 1/4in. We send instructions on application technique, too!
