This Concord 20-Part 1-20 Multicolour Index provides numbered organisation to A4 lever arch files and ring binders. They offer a bright, colour-coded way to organise your documents with numbered tabs and an easy to use index cover. Each divider is made from strong board with Mylar reinforced tabs and holes to protect against rips and tears. The tabs are numbered for quick access to sections, punched with 4 holes to fit most lever arch files and ring binders, and extra wide to display tabs clearly when using punched pockets.
