Able to write notes in "small font" with edge of tip and "big font" with width of marker. Suggestion: Perhaps make a 4-pack with 2 colors of 2 qty each or a 6-pack with 3 colors 2 qty each.
I'm a full time college student and I use highlighters while taking notes and reading books. These highlighters work amazing and don't smear the text in books or on printed paper. Fun colors too.
