Uni Pin Drawing Pens/6 Assorted Tip Sizes, Uni Pin Technical Fineliner Pens, Pack of 6 Assorted Tip Sizes, Black Ink

I personally like them better than microns! Very durable. Nib doesn't bend too easy like other brands!

Teen son has been using these fine-liners for awhile and they seem to be holding up quite well. He's used them on mixed media paper and other sketch pad paper, and they have not bled through any of his drawings. He's used them along with colored pencils and alcohol markers without any issues. He advises to let it dry for at least 2 minutes before erasing sketch lines or coloring. He's very satisfied with these and they've been a terrific addition to his art supplies.

I have used several types of pens for my art projects. Seeing this product on YouTube being used by an artist inspired me to purchase a set of pens in various sizes. I am so glad that I did. I have used Micron for years with a few others thrown in, but this product surpasses them all. Smooth application. No fighting the paper...I used them on watercolor paper over watercolor pigment. They withstood the test. On less rough paper they breeze through the sessions. The color is dark and waterproof. I wish I would have found them sooner.

I've always been a copic pen person, but was looking for something less expensive for my daughter who is just starting bullet Journaling. I tried these out, and loved them so much my copic pens have been left in the drawer and not used. They are an incredible price. They dry very quickly, and haven't smudged at all, even after erasing pencil. They layer perfectly on colored pencils, mildliner etc. I have a heavy hand, and the tips have held up very well and no extra ink on edge thy edge of the ruler.You can say they are my new favorite pens!

Anytime I buy something inexpensive on Amazon, I worry that it will be terrible quality. Although this is one of the cheapest options for this type of pen set, it works extremely well.I have a light touch when I'm writing, so for me, these pens use just the right amount of ink to make even small writing readable.The ink doesn't bleed at all. It dries almost instantly, no matter how hard you press. It also doesn't bleed through the page unless you use a lot of ink.The only thing I don't like is that the numbers on the top of the pen cap wear off easily. I left a photo to show what I mean. Only one has worn off so far and I keep them organized in the same case they came in, so I can still tell the difference between them, but if all the numbers wear off, it'll start getting confusing.

My rankings of top writing pens (all deliver excellent overall line/ink quality):1. Mitsubishi Uni Pin Fine Line - good grip, darkest black, best glide, very good precision2. Staedtler Pigment Liner - best grip, ok black, ok glide, excellent precision3. Sakura Pigma Micron - mediocre grip, ok black, ok glide, top precisionNote on grip -- I tend to hold pens fairly close to the nib, the farther out you hold the pen, the less of a difference there is between these pens.Overall, my default pen (or especially if I want to write quickly) is Mitsubishi Uni Pins because they glide on paper the smoothest and the ink looks the richest. When I feel like more like using a slightly more comfortable & precise pen, I switch over to the Staedtler Pigment liners. While the Sakura Microns are still excellent pens overall, I no longer use them because they lose in grip comfort to the Staedtlers, and lose in everything except precision to the Mitsubishi Uni Pins.

The media could not be loaded. Quick drying, vibrant color, doesn’t bleed through , waterproof! Perfect pen for my Zentangle drawing! Been recommending to other tanglers in social media!

I purchased these pens (both the ten-pack and the six-pack) for drawing and urban sketching. I have not been disappointed with the quality of the pens and how easy they are to use. The boldness of the thicker pens’ lines is great and the fine pens create the light lines often needed in drawing. However, when I tried to use watercolors to enhance my urban sketching, I was disappointed. The company’s description states that the pens won’t bleed once the ink is dry -- I did not find that to be true. I waited over a week to try to add watercolor to one of my sketches but, after testing a small area with a damp thumb, realized that the ink bleeds regardless of the ink being completely dry before testing it. These are great pens if your desire is to use them for sketching but I’d stay away from them if you want to add watercolor to those drawings.Update: I inadvertently used watercolor paints on several of the sketches I made with these pens — and there was NO ink bleeding. Since the first watercolor painting, I’ve probably made a dozen more and the ink remains waterproof once dry. I upgraded my rating to 5 stars and am delighted with these pens.
