I am very impressed with these pens. The ink flow is steady but especially so when holding the same pressure as you write. The quality of the ink is exceptional and fairly priced for the 3 pack this came in. I would definitely buy this again.

The absolute best pens ever for marking dark fabric. They run out of ink faster on fabric, but it’s worth it considering it works so well. I use these pens on all of my black and really dark fleece and minky. They’re also great for effects on art pieces, even over layers of caked on colored pencil wax (just don’t touch it for a while so it can set!) The ink is exceptionally thick and opaque, and these pens are well worth the money. The silver metallic versions are just as good if not better.

These work so well as a highlight and for little details while i'm coloring in my books. You do have your let it dry or it will smudge, but it dries fairly quickly! They go over black outlines easily and stand out on any color (:

Works great over alcohol marker; shows up well. Great for coloring art.would be great on black or dark paper for greeting card making. 1mm thickness lines. Easy to use as a ballpoint pen.

The pen is nice and the ink rolls beautifully, but against white coloring paper the ink is tinted visibly yellow.

Amazing pens very smooth & opaque. Purchased on recommendation of another artists. Highly recommend them.

I have used these pens for years and they are great. Ink flow is good. Color is pure white–as the ink gets low it may dry on the tip but I just wipe it and good to go. Perfect for highlights and outlining.

Good in flow, it doesn’t like or bleed to much. Unlike others you don’t need to press into it and control how much ink is coming. It covers bright well on all colors. Easy to use. Good quality.
