This is an OEM refill supplies kit for the Smead Straight-Line Viewables Labeling System, containing 100 tabs, 112 labels, and 112 label protectors. These supplies allow you to create unique labels that attach to specially designed, patented three-sided hanging folder tabs. The tabs can be read from the front, top, or back, facilitating faster filing and retrieval. The use of color breaks your system into smaller sections, helping to highlight misfiled folders.
