Great color, smooth flow.

Love the color of this refill, a little darker blue. It has a really nice smooth flow to it. The only issue I had with it is that it is a little heavy in regards to ink flow. While using Rhodia notebooks I get some ghosting, but I do have a slightly heavy hand. I would imagine thinner papers would have some bleeding. I am going to use this refill to replace all of my original Retro 51 roller ball inks.
