Here is an unopened roll of Noah's Ark 6-3/4 inch wallpaper border by Sunworthy. The pattern is TTCS1086B.
The wallpaper is 6-3/4 inches wide and 5 yards (15 feet) long. It's a self-stick removable border. It works like a giant sticker. You don't need to use glue or dunk it in water to activate the glue. This is the easiest paper you can find for both application and removal.
I bought this wall paper secondhand and I am not an authorized retailer, so I am listing this as "New, other." The package is still wrapped and in unused condition. The wrapper is a little torn as seen in the photos, and the wallpaper underneath looks nice and clean. The product information printed on the packaging says it is 5.75 inches tall, but I measured it, and it's actually 6-3/4 inches. I'm afraid this is the only roll I have.
