Love the fineness! Love the colors! Just have to be very easy on them. I can't use a couple, except keep them as straight up and down as possible. I've had problems with pen and pencil pressure my whole life. Just be gentle. But. They are very precise.
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.
