 Magnetic Dry Erase Signboards
The humble magnetic dry erase signboards started out life in the sales and marketing industry many years ago, as a replacement for using a permanent marker on large sheets of paper for sales managers or speakers to make illustrations and notes to groups of medium size.
Previous to the magnetic dry erase signboards, their only choice was to pack in a very heavy chalkboard and use regular chalk, but that was seldom feasible, especially when traveling. Their next choice was a large tablet of paper attached to an easel, on which, notes and ideas were made with a permanent marker or grease pen. On the road for any length of time, a speaker or manager could require 100's of pounds of paper in the form of tablets of large format paper.
With the advent of the dry erase marker and the magnetic dry erase signboard this all changed. Now, ideas, notes and images could be applied to a light weight magnetic dry erase signboard, then easily wiped right off with a dry towel or regular eraser. With these markers, the magnetic dry erase signboards could be used over and over. With no heavy chalkboard, no messy chalk and no reams of large format paper to have to deal with, magnetic dry erase signboards were an overnight success.
It wasn't long until educators discovered the magnetic dry erase signboards for classroom work. First for the teacher in general lectures and lessons, but, eventually, for the student. Since magnetic dry erase signboards were cheap and light weight, even small children could have their own personal 8"x 11" whiteboard tablet to work on using a non-toxic, low odor dry erase marker.
Of course, today magnetic dry erase signboards come in a myriad sizes and shapes. There is no doubt, magnetic dry erase signboards are the most common type of signboard manufactured in the world.
