This Concord 12-Part Jan-December Multicolour Index provides organisation to A4 lever arch files and ring binders. They offer a bright, colour-coded way to organise your documents with alphabetically labelled tabs and a 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 labelled for quick access to sections and they are punched with 4 holes to fit most lever arch files or ring binders and the index is extra wide, so you can still see the tabs behind punched pockets.
