I moved in June of this year, and I bought this to prevent my dog from chewing on the walls of the new house, but he didn't chew at all, so I only used about 1 meter of it. Therefore, about 5 meters are still left. I also have 4 corner protectors remaining. Several months have passed, and they are still attached to the wall without coming off. They tend to trap air bubbles, so it's best to press them down firmly! Please consider it.
