Presentation blinds wind down directly against a wall, so that the blind can be used as a writing surface, with the support of the wall behind. As they consist of a opaque white pvc backing sheet with a drywipe clear plastic front sheet, this creates a pocket between in which any paper resource can be slotted and highlights or notes can then be overdrawn onto the plastic surface. A cheap and flexible way to make presentations and which rolls up unobtrusively when not required. Ideal for schools and small businesses.
