    These pens are the pens that we prefer to use at our work. The pen writes smooth, and doesn't make dark ink spots. You are able to write on a paper in the rain, even if the paper is wet.Makes writing effortless. I love that is comes in so many colors. We have red, navy blue, light blue, purple, red, pink, green ect... Like I said, they are the most loved pen at my work.The only down side is that you will need to buy more because anyone that uses will not give it back to you.Tip of pen is metal, but it is not sharp enough to cut or tear the paper. Pens do not leak or bleed.I have bought these pens over and over again, dozens of times. We will continue to do so!If you war debating, do it. These are the BEST PENS!

    These are my fav writing pens . The 0.7mm tip is perfect for me because it produces medium lines (perfect thickness) and very smooth ink flow, which I find ideal for everyday writing tasks. I love the clear and easy-to-read writing these pens produce.One of the best features is that the liquid gel ink dries super-fast, so I do not have to worry about smears or smudges. I hate that! The pens have a stylish barrel design with silver accents, giving the pens a professional and polished look. Another great feature is that these pens are refillable, which makes them a great deal over time —assuming, of course, you manage not to lose them Lastly, the soft grip makes them very comfortable to write with. This is perfect for long writing sessions because they are easier on the hand.

    I spend way more time typing these days, so I’ve come to really appreciate a good pen, and this one’s a standout. The 0.7mm metal tip delivers a smooth, bold black line that’s crisp and consistent—perfect for notes, sketches, or anything I need to jot down. The gel ink flows effortlessly and dries fast, so smears aren’t an issue, even when I’m rushing. A great pick if you want a quality writing experience!

    These are wonderful gel-writers for even the most finicky writers. Very smooth and quick drying gel pens with a nice variety of colors. The grip is well-no slide for precision in writing letters or journals. They are long-lasting and have a great quality ink. Will work for lots of surfaces and paper types. The price can’t be beat with these. I got a M 0.7 mm line in black, pink, green, blue and purple. All these are vibrant and easy to see with a medium thick line.
