This Concord A4 10-part extra wide subject divider is wider than standard dividers to accommodate punched pockets without hiding the dividers. Supplied in plain white, handy tabs separate documents into sections and are easily written or typed on for identification at a glance. These dividers are made of strong 160 micron board, making them the hard wearing and functional choice for students or businesses. Standard Euro punching fits almost any A4 ring binder or lever arch file.
