Size matters! these tabs are great because they are larger than the paper that will be placed behind them. All you see is the tabs--they don't disappear because of the notebook papers placed between the tabs. Also the pockets are very well reinforced--aids to quickly place extra stuff in a time crunch.
My office has literaly "millions" of tabs and dividers for 3-Ring binders but none of them have tabs that extend past Document Protector sleeves so they all suck. This set doesn't suck because it has five of them.
