Technology has made it possible for us to have portable gadgets that would otherwise require you to do stuff in a fixed locality. This even applies to the gadgets that we use in our classrooms. For a long time, schools have used writing surfaces which are fixed on the wall, making it impossible to move them. Others had a long frame or stand made of metal, on which the surface on which one wrote rested.
These classroom writing surfaces have today been replaced by what are called the dry erase boards, which are white in color, and furthermore, they do not make use of chalk but instead use alcohol based markers. There are those of them that are not only used inside a classroom, but they can also be used outside the class setting. They are the portable dry erase boards.
What makes them portable is the fact that they are light in weight and that they can be easily hung against any surface. You may also want to know that it will not cost you much to acquire them because they are sold cheap prices. When you hang them, there is a double locking mechanism that holds it in position and prevents it from flipping until the need to do so arises. It is also possible to adjust the height to the desirable length.
The materials the portable dry erase boards are made from also ensures that the object lasts long and is not worn away by the ink that you use on the surface. They also come with storage spaces. There is a middle tray that holds the writing tools and other items that you will need as you make a presentation. The tray is located at the bottom frame of the surface.
