This is a great item. You use different colors to answer the questions - who, how, where, why and black to write notes. It is a wonderful study product, to learn about the Bible. You underline the answers with different colors.I wish I had known about it years ago.
These pens are nice. I like the color coding, and the fact that they are flat. They are in a "cd case", so that makes them easy to carry with you. The main thing I don't care for is that the ink is so light, I have to underline 2 or 3 times to see the color. Since it is a pen, you can see the mark from underlining on the other side of the page (kind of like a bubble). So if you don't want to have that problem, the dry highlighters might be a better choice.
