Specialty paper provides the convenience of detachable sheets for training manuals and workbooks or detachable replies for invoices, return remittances and announcements. 20 lb. multipurpose paper is 19-hole punched and designed for use in binders greater than 1/2". Quality controlled to ensure no paper deformation around holes or loose holes within a ream. This translates into fewer paper jams.
