Letter sets are printed tabs that are sold in a pack of 26 consecutive letters from A to Z, offering the entire English alphabet in one pack. They offer a simple and effective solution for filing your papers of any kind. They are collated into a set and you can see all 26 letters since they are in one bank. You can choose from single side or bottom letters (like "A") or double letters (like "AA"). All of these indexes are Avery style, which is the most popular kind of printed tab. They are made on an 80# bright white index, printed in a Helvetica bold, all-caps font on both sides, and have a clear mylar coating added to the extensions for added durability. There isn't an easier way to sort and organize paperwork than by using a basic index tab divider. At Binding101, we stock a variety of pre-printed letter indexes that make filing simple, and clear.
