It also works on concrete walls
Construction professionals know this well: marking walls with a pencil is often necessary for taking measurements. After finishing work, these marks should be removed.

Can be used on wallpaper (with care)
This is a little-known but sometimes very useful trick. In the case of writing instructions directly on a wall covered with wallpaper, it may be necessary to remove them later.
