magic tree / scale

When mounting displays on the wall for exhibitions or art shows, people usually climb up a ladder to mark the locations or use a lengthy ruler. However, errors frequently occur when using a lengthy ruler since it is difficult to accurately measure vertical lines, and, whining using a ladder, there is a difficulty of having to move the ladder whenever marking different spots. Magic Tree, which started from a concept to conveniently assist preparations for exhibitions, allows the users to easily mark on the wall of desired heights for display mounts.
