Vibrant colors and smooth lines.

They are smooth to draw with and the line if quite fine

They have a very fine line that is precise.

They make crisp, clear lines, and the small tips are great for getting in small spaces.

I especially like that I can write a nice, crisp line which makes them ideal for writing in the small spaces of my planner.

They are very slim to hold (perfect my small hands), and although the line is quite fine, the colors are intense (as advertised) and show up beautifully for coloring in coloring books, artwork, or just writing.

I also use these in my rock painting projects...just need to let dry very good before sealing...put out a nice thin line!
