The pen set I received consisted of 1 each of dark green, black, green, and red. This is not what is listed as the product listing. Opening the plastic package was hard since I was trying to keep it as a container for the pens. Once I cut the two spots where the plastic was welded, I had no trouble. The markers work as described and I'm pleased with them.
There are reviews of pens for the Bible and Pigma Micron are known as the best on the market. I especially like the blue color because it is a good contrast to the text whether red letter or black text. On good Bible paper it will not leak or seep through the paper as long as you do not press too hard.
Archival ink means that your notes will last and not fade or smear. So far, the pens have been just as good as the reviews have stated. If you want to save money order your pens from Christian Book Distributors.
These pens are nice, I have used them for a long time now for taking notes in my bible. I ordered the 005 pens this time, and they are just a little to fine for me. Next time I will order the pens that are just a little thicker-but that's just a personal preference.
