They come in a pack of 12, and as you can see there is a great variety of colours-it's not obvious from this picture, but no two shades are the same. The is also a sheet of clear stickers with every category you could imagine, as you can see above. You put the stickers on the little tabs! I still love my Adelphi dividers, but they have been taking a bit of a beating, and getting a little ragged around the edges. I was thinking about using a different type of divider, and saw these. Since they are plain white, I had the idea I might do a sketch or drawing right on the divider itself.
But, even though the tab is nice and strudy, the paper used for the divider is just that...paper! It's the thickness of a normal piece of paper, which I find too flimsy. However, for those of you who like to attach images to your dividers, these would be perfect!
Also, upon putting one in my Adelphi to try it out, I discovered that the tabs don't protrude out from the pages very much. They are very small, as are the little clear stickers with the categories. I think they would be more appropriate for a slimline or compact... I like my tabs and category stickers to be nice and bold...but I'm keeping them, of course. You never know when a Filofax-compatible accessory might come in handy!
