I used these tabs in conjunction with the Avery sheet protector tabs to produce my husband portfolio. The sheet protector tabs were used for the major sections and the index tabs were for the catagories within each section.I also used the same system with my teacher portfolio and it worked beautifully. Each section was seperated by a sheet protector index tab which allowed artwork insertions, and then the 5 tab catagories.Superb organizational index products. They come in bright and pastel colors.I've ordered these in the past through another vendor and for some reason the ones thru Amazon don't appear to be the same thickness. The sheets seem flimsy and tear much more easy than with the older version. Not sure what;s up. Obviously they are not as strong.I use a lot of dividers in my work, and these are among my favorite. They come in a couple of sets of colors and the tabs are easy to print out. No more jamming paper into tab slots. And Avery has software for free that lets you format all their product.Box had been previously opened and was in poor shape, however the dividers were fine.Works as advertised. No complaints. In fact there is an additional label sheet in the package that isn't even mentioned in the contents list.These are great!Great price for the product. Beats the heck out the Office supply stores.Very good. True to the description
