Hello, I've been using Pilot Metropolitan as a beginner fountain pen, and few days ago I ordered a Parker Premier Monochrome Black Edition to make a upgrade. And when I tried to write with it I noticed that the ink is not coming out as well whenever I write. Would this be a ink problem or the nib/pen problem? I'm thinking of returning this pen if it's the pen/nib problem. Here is a example of what I'm talking about It's little hard to see in the numbers, but in the second slash you can definitely see the gradient. it's little gray on the top then more dark on the bottom. Can someone please help me and let me know what I should do?
