Since they're see-through ~ you know when they're going to run out. Colors are vibrant. Chisel tip works well and they are a go-to office supply at a more attractive price than some of the other brands. Typically I'm not interested in budget shopping but the price for these can't be beat.
Was looking for a highlighter set that had a lot of colors you could still see through the colors and the ink didn't run. Was able to test them in the store and so far (have had them about a month) they are exactly what I was looking for. You can also see the ink level. The only reason they didn't get 5 stars is because I haven't had them long enough.
