I’ve used a number of different dividers over decades. I like these (the 5 and 8 tabs) the best. Been using them to organize Ancestry info. It is so nice to not have to depend just on reading the small print on a divider label to find a person but to also be able to flip to a tab and see through it and be able to read what is written on the first page behind that tab. I really like the shape of tabs and color scheme. Not the usual pastel or all white or bright pink yellow etc. or rounded tabs with less writing space. These tab colors have a nice professional look and feel to them and are quite durable.
I love these clear/colored notebook dividers. They make it really easy to see what is under each tab and they keep my paper protected for any accidents or spills.
