The preferred material for the planar sections or panels is corrugated paperboard (i.e., “cardboard”). The preferred configuration includes four connected panels which are sized to create a square-shaped holder when the panels are moved to their fully expanded condition. Two opposite panels are scored vertically along their mid-regions so that they may be folded internally until they ...
