TWO-PIECE FOLDER

The two-piece folder is made in many different sizes, and consists of two straight-cut sheets of corrugated board which, when folded together, form a closed box having four flaps at the top. The flat pieces, which are scored, are sent to the customer who folds and assembles them as needed.
