This Concord 31 Part 1-31 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 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 numbered for quick access to the relevant section when looking up files. They are punched with 4 holes to fit most lever arch files and ring binders and this index is extra wide, so you can still see the tabs behind punched pockets.
