Nice, colorful journaling pens.
I loved these pens for journaling. I enjoyed all the different colors and the general quality of the pens. I could use certain colors to help get a seasonal or holiday visual for the month. They have a nice, fine point for writing small, if needed. They did not bleed through the paper. The ink flow is smooth and does not skip or fail to lay down. I did not have any problems with the ink drying time, either. I like that the tip retracts. I also like the easy grip surface of the lower portion of the barrel. The only problem is that I wish they sold sets of multi-colored refills. Journaling uses quite a bit of ink, and I sure do not like to just dispose of the whole pen when the ink runs out. That is not environmentally friendly. And, it will be confusing to just put say blue or black refills in all pens that have different colored tops.

Super fine
These pens come in nice colors. The level of pigment in each color is perfectly opague, not see through or weak. At .38, the ballpoint tips are very fine and serve their purpose well when it comes to having to write in small spaces or your particular handwriting style is to write in very small print. This also makes them perfect for writing notes in the margins of your favorite book or Bible.

Smooth writing, great colors and great quality
I LOVE these pens! Smooth writing, great color, which helps me organize my daily work. The .38 ballpoint helps when I have to write small and clear. As a teacher, these are part of my go to supplies. Yes, I have to buy my own supplies and this is why I want quality, great prices (when on a sale) and the colors. The colors add another layer of organization throughout my day.

Pretty nice pens.
They are pretty good pens. I love the design. There is some skipping so I have to scribble a bit before using them ( however that might be because they are still new) there is no bleeding just slight ghosting and rippling on my stalogy notebook ( which is really thin paper, so it would be good on normal paper). The colors are nice and vibrant.

Great pen
I buy too many sets of pens. Thus far these are my favorite fine point. They don't leak, they haven't run out, and the colors are true.

Love them, will repurchase when done!
They glide so smoothly and I love the array of colors. I'm studying BR portuguese and it's so satisfying to write with these pens. It gives me less excuse to be lazy! Writing on regular paper these do not smudge at all even if you rub the words right after writing. However, like most gel pens it smudges when you write on glossy paper.

Lefty friendly perfect for hobonichi
I’m left handed and it’s super hard to find pens that don’t smudge immediately. These pens are great for lefties. The colors are vibrant and they don’t bleed through hobonichi paper. They write smoothly

Used pens
Colors are bright and stand out well on hobonichi paper. Only issue I had was the pens were not new. Three of them had the wax already removed or partially removed.

The ink felt really smooth on paper. Glides very easily. Fast drying and does not smudge easily. If you prefer a heavier/sturdier pen, they have the a few options with heavier bodies. I prefer those for prolonged writing. This set is great for making notes, annotating, even drawing. Will buy again.
