Leaky 4-Color Pen

For some reason, my four color big pen was leaking black ink. So I threw it away, and on my way back from a conference, I stopped by an Office Depot and purchased a new Big four color pen full stop actually I bought four of them. The reason why I went out of my way to write this down, is because there was a different brand there was a new one with a new ink formulation that is supposed to have a smoother ink flow. I really enjoy the original four color big pen, but and because I'm so familiar with it, I wanted to see how well this one compares. Does it look different?
