I love these markers. I'm a resin artist so resin is the only surface I've used these on, and they work beautifully. The ink dries very quickly, yet you do have a minute to gently wipe a "mistake" away with a little alcohol, if needed.The red is not a true red (red is a tough color in general), it's more like a cross between red and burnt orange, and the yellow is more like a very light lime green. There are several versions of some colors and there is no black-- just a very dark gray. But the "metallic" quality is obvious, and the gold, silver, and copper seem "true".Most of the work I do is very detailed so I primarily use the fine point. When I received my markers and worked my way through them, I found that three of them had a kind of "retracted" fine point. The point was still usable, but I couldn't get into smaller areas of my castings. I wrote to InkLab and not only did customer service respond right away, they apologized and sent me a new set! All of the fine points are intact.Excellent product and clearly the company has an attentive and caring customer service department. Thank you!
