Someone I work with introduced these to me and I LOVE THEM! You need a permanent fine point sharpie to write on them. I use both small and large tabs. The regular blue and red are not enough contrast - difficult to read, so I prefer these lighter colors. I would like to see larger variety of colors in one pack. Packs of 24 and 30 is not sufficient. People that care about color-coding like consistency - suppliers need to provide it. I prefer the ones with a dispenser. I can remove a tab to make a copy and put it back on, or if I get a more recent invoice I can put the tab on that one to start my section and it adheres well.
