I bought these on a whim to get my I purchase up to the $35 for next-day shipping. Now they are my favorite colored pens. I really like colored pens both for creative uses and taking notes at work. Everything moves at a very fast pace, and I can easily spot the different sections by their color.The problem with most sets is that at least a few of the pens are in colors that you can barely see if you write with them. Not so with this set! Even the lighter colors stand out against notebook paper sufficiently to take easily readable notes. I love that!Also, I was surprised and impressed by the rich, smooth, luxury feel of writing with these inexpensive pens. There is not a bit of dragging or scratching on regular lined notebook paper or unlined drawing paper or cards.The only thing that might be an issue for a small percentage of people is if you use Tomoe River paper, such as in a Hobonichi planner. In that case your hand will smear the fresh ink as you continue to write if you aren't careful.This is not the fault of these pens. Tomoe River paper is wonderful, but choice of pen is important with it. I have a variety of different paper types and that is the only paper type that had any issue, and even that is not insurmountable. With every other paper type including the more luxurious papers (I'm a nerd about pens and paper) these pens give me a really nice color and clean lines with no smearing, and they can even fill in at least small areas of coloring without visible coloring lines. I really recommend giving these a try. The price on them is really great, and they are a joy to use. They are more versatile, too. I expect I will continue to purchase this type of pens going forward.
