Sort, index and organise. Every document can be kept in order with the help of alphabetical and numerical indexes. Kill two birds with one stone – it will be easier to know where to put your documents, bills, etc. and a lot easier to find them again should the need arise. Our files and binders come in a number of sizes and have different kinds of ring mechanisms. The subject dividers and thumb indexes we sell are universal and have multiple holes along the margin to enable them to be used with different types of ring binders having different numbers of rings.
